Yes, in BLD you solve stickers rather than pieces.
I've made up letter pairs. I understand the Speffz letter scheme. I can execute witg classic pochmann method. But I still don't understand how to memorize the cube. I don't think there are any good explanations for this or any good examples on this. Idk if it's just me who misunderstood smth.'x. Any tips for me guys? I really want to be able to solve 3BLD.

You have asked this question already. Simply memorize the sticker (R) on your corner, then (T) for the next corner, then you will have to make a word, for example: Rabbit.
Also, there are loads of good explanations on youtube.

Example:
R2 D2 L2 F2 D F2 R2 D B2 L2 U' L B' U2 L B F' R U F D'
(before scrambling, orient your cube like you would for BLD. So don't use white top green front - unless that's what you use for BLD of course)
Corners:
The buffer is Ubl. The sticker at this location is P. Memo P. P = Rfd, so look which sticker is at Rfd. This is B. Memo so far is PB. B = Ubr, so look which sticker is at Ubr. This is I. Memo so far is PBI. And so on... PBIXU is the first cycle (because the sticker at U is one of the buffer piece, so the cycle ends.) I choose to start the second cycle with C, so the second cycle becomes COM. Full memo = PBIXU COM.

If you want a ULB buffer, OP makes it very easy. Just use OP for any cases that you can't solve with comms and then gradually incorporate comms into your solves.
I don't know how people switch to different buffers. It seems that a lot of the fast people use UBR though.
I wouldn't worry too much about how fast your individual times are. Just focus on removing pauses and you'll probably be fine.
But how do you memorize PBIXU COM. And how do you know that they are all twisted right at the end?

You might not be ready for BLD yet. Try scrambling a cube, writing down your letter pairs, then solving it using those pairs. That will help you find where you are making mistakes.
Edit: You said you had letter pairs memorized. Break up PBIXUCOM into (PB)(IX)(UC)(OM) which could be Peanut Butter, Ice Box/Index, UC would be UC Boulder (school I am going to), and OM would be oatmeal. Obviously you can have different words, but yeah....

I'm really sure that I'm ready for BLD! I can recite 200 decimals of pi with memory without using images, im sure the memory is not the problem here. And i have a lot of experience with the rubiks cube, my times are 30-45sec. I just know there is something im missing, and i cant really find it explained clearly enough anywhere. If I use "dragon" as memo for "DR" and my piece has red/blue stickers, how do i know its flipped the right way when i swap it in the buffer place, and put it where its supposed to?

Look at my previous edit, btw. If you have two edges represented by the letters (D/E) and (A/U) as I do in my scheme, you would know the orientation by memorizing either DA, EA, DU, or EU for your OP cycles. Same thing works with corners, except there are three possible stickers.
I'm really confused with the difference between Speffz letter scheme and just the normal like DR = down, right. Why do we need the letter scheme? It was to make letter pairs right ?

Watch this series. You really need to understand these basic concepts before you are anywhere near ready for a bld solve.

Congratulations, but I would like to inform you that 200 digits is not a big deal with images and memory techniques. That is why we use them. I know that some people manage to brute force a lot of digits of pi, but it takes about 5 minutes to memorize 200 digits with techniques and that is why we use images for BLD. Another benefit is that you will continue to improve with images, but rote memory does not improve very well with practice.
BLD solvers label each sticker with a letter. If the sticker is put in it's place, then the other sticker will automatically be correct. Do sighted solves like what was mentioned before. This will get rid of any doubts about execution which will only clutter your mind during a solve and then practice.
Yes but I memorize 200 without any techniques, I'm memorizing them simple by remembering the numbers. This is why i think its ok.

That would be inefficient, slow, and inaccurate with BLD memorization.
I'm new to image techniques, I'm trying to learn it with those BLD tutorials.

You would use the same letter pairs for corners and edges, both piece sets have 24 targets. The actual number will vary based on if the same letters are in your buffer or how you decide to make images out of fliped pieces. You would need about 440 images since that is the number of cycles for edges. There are 26 letters in the English alphabet so the total set of possible letter pair images is 676. I have an image for every pair because I felt like completing the list. I would suggest staying away from x though since that was the worst letter to find words for. Y is better.

You don't actually need all the letters though. Something I did when I created my letter scheme was to make Q my edges buffer so I don't need to use letter pairs involving Q
