That's absolutely not true. Go watch competitive Starcraft, competitive Overwatch, competitive Siege, etc.
If I put you into a game with an pro DBZF player, you'd get turned into absolute Swiss cheese. Technical execution, frame knowledge, set ups, understanding the nuances of the game, etc.
We've seen guys like Daigo struggle as they get older, despite being revered as gods of their craft, because their bodies simply aren't as quick anymore.
The skill level is stupidly high in these games. Things average players don't even take into account or know about matter HUGE in truly competitive play.
This is stupidly hard to do. I can't even put it into words how quick he's moving and the decisions he's making while planning against another human opponent who has his own plans. There is nothing low-skill about this.
The average player maybe does 2-3 actions per minute. Championship players do up to high 200s or low 300s APM.
Believe me. In most e-sports, they're playing against other humans and not dealing with the AI at all
