To be frank, there is really no educational requirements to be a professional Esports player. Actually, many of the players dropped out of highschool or college to join their respective leagues. Being in Esports takes all of your time, and kids are recruited at a relatively young age. Now, to be a caster, you have to be good a speaking, and have very good statistical knowledge of your game. But, you don't necessarily have to go to school for that.
