I haven't seen any evidence to suggest 30 years is a number of much importance for this. Most Esports scenes also aren't old enough to have older players as well. The only ones that I know of are Quake and Street Fighter. In Quake currently only 1 or 2 of the best mechanically gifted players in the world are under 30. In Street Fighter, there's a wide range of ages including younger players as well as players as old as 40+. The "god of execution" Sakonoko is 42 years old and is still winning major tournaments every once in a while. In Formula 1, Lewis Hamilton is likely on his way to yet another world championship at 36, edging it out over his 10 years younger contender.
