Am I mentally handicapped?

I have been drawing for a long time, but everything I draw properly feels like pure luck.

I have produced many okay-looking finished pieces, but when I try to study, pic related is what happens (numbered in order of drawing).
I copied the process step-by-step (video here https://youtu.be/q3kfG7_8Mbg ), with #1 and #6 being the best ones, even though I drew #6 with the WRONG HAND.

What gives? What should I grind to fix this brain damage? Is anyone else like this?
I drew in pen, meaning no Ctrl+Z, but I (think I) tried to be careful about where I put things - it didn't matter, clearly I can't eyeball things to save my life.
