Well take someone who YOLO on a 0 DTE option and makes 80x (not unheard of) vs someone who wins the same amount over, say, four years and 8 000 trades... Well it's not impossible that the YOLOer is more skilled and has an edge (while also being a degen but that's not the point): it is just very unlikely.

Thousands, tens of thousands, hundreds of thousands of trades is not the same as "gambling one night in Vegas".
