Why is skydoesminecraft so famous?

I'm not trying to be a hater but just wondering haha.
Sky has like 10 million subs but how does he get so many just by playing minecraft?
He just screams and invented the budder thing and jokes around while playing minecraft minigames over and over again.
Like for example Bethany Mota doesn't even have 10 million and I think someone like her deserves 10 million.
So ya I'm not hating ok just wondering xp
