Its not really counterintuitive, the prime years are lower because true physical development in physical sports starts at a later age, everything up to that point is related to building a physical foundation for movement, building an interest in the sport, and laying groundwork for proper mechanics.

There is also societal stigma from playing video games seriously past early 20s(well atleast 5-10+ years ago, but with Twitch and things it is now way more accceptable).

"Reaction times in traditional sports are not as important" is laughable.
