The famous top players are Chads. Not because they are better at the game, but because they are more popular. Remember this, your actual skill or ability doesn't matter at all in our society, all that matters is how other people evaluate you. This is why a super qualified person whose work is basically pulling a company can end up being paid less than a diddling manager who spends all day spanking his secretary and smoking cigars.
It's like a feedback loop. The popular top streamers get a ton of money and validation that encourages them to continue playing the game and getting better. Meanwhile, in the case of a truecel who might be objectively better skillwise than them, no one cares about how good he is and people call him a loser for playing games all the time. Eventually he inevitably gets bored of the game because there's nothing in it for him.
