Competitive games are complex. It's hard to be 95% percentile. There are so many mistakes one can make, even if each individual mistake is unlikely, it's likely that a mistake will be made. I participate in Dota 2, and literally everyone makes noticeable mistakes, even including tier 1 pro players and the top ranked pub players. I honestly find it amazing how good people are given how complex the domain is.

Now scale that up 10x, because reality is at least an order of magnitude more complex than a video game.
