>3. But another factor is less reaction time and more that the late 20s and early 30s players have spouses and more expansive lives beyond the game, so they simply cannot spend the 100+ hours a week perfectly tuning the midlane or hard carry meta where the fundamentals can change really fast. Also, for the most successful players (read: millionaires) they want to enjoy their wealth and do things outside the game. I think this is the biggest factor in the same way most devs don't stay in the same job for 20 years (particularly the top ones!). Additionally, most games change a lot over their lifespan; what made someone a top player in the early days doesn't necessarily continue to benefit them now, and mindset/skillset changes are not easy to make. Poker is a great example of that: pros from 20 years ago might have experience, but if they're not up-to-date with the cutting edge of theory and solvers, their 'experience' will get them crushed.
