Do top world wide players are actually top?

Recently I started watching streams of warzone nominated "top world wide players". 1st i was curious to see and learn how they got that many kd, e/d, wins. But sadly I started noticing many do 2box, if they get clapped by any player they just exit the lobby (they even lost with some 22 level players multiple times in 1v1). It's just feels like they are only here to play to keep up their name by these cheap tricks.

But some famous streamers (not on the warzone world wide top list) play better than these guys.

What are your thoughts on "top players quit in the middle" if they feel players are skilled than them? I find hard to accept that they are running away from lobby like a little girl.
