Idk why I was suddenly reminded of that song... Makudonarudo Guguru Toiletto Kitto Katto Dizunilando Takushi go Hoteru Sebun Elebun Miruku Basu Biru Sutabakkusu
even if they don't, most esports players honestly just go back to college. it's why there's been a larger push for some players to compete during or only after getting their degree.
if they're super young they probably go back to school. If not they can always become an analysts, coach, work in esports company, or become a caster like steele.
It's just depends how u branding ur self
There's always characteristic of streamer it's self
Also I believe if ardiis want become streamer he can growth (but he can also have fast drain and become burn out so easily because of the character himself)
some may become analysts, casters, coaches, streamers etc
some try to invest during their career to have a money buffer for retirement
some get degree and a regular job
