If you didn't intentionally auf your dot EO so you would skip CO then yes i would count that as lucky. Also, if you normally use 2-look PLL then U perm or any EPLL is also pretty lucky. Skipping 1 or more steps in LL = lucky. Lucky F2l is more difficult to define. Skipping a single f2l slot by unintentional multislotting or accidental xcross isn't enough to make an f2l lucky in my opinion. To me that's less lucky than getting 2 or move 3 move pairs or getting a rotationless f2l with very easy lookahead, where the next pair is right in front of you every time.
If you knew OLL/PLL then it would definitely be full step. 2-look OLL/PLL is pretty much full step if you knew you would skip CO with 2 F sexy's. 4LLL is certainly not full step.
