Warzone Skills match up

I just started to play call of duty MW a couple of weeks ago. I’m still wondering how they make the player’s match up in the battle royal. My guess is, there’s no selection, they just take 150 players randomly to make the game. That makes a whole world of difference between the skills level of every players. I know I have to be better if I want to win, but still, is it to hard to play against people who has the same skills level than me ?
