The selection of players (Call of Duty: Modern Warfare (2019))

The question is: when will I wait to the selection of players was the ability to play. I mean, I'm not very good and I hate that I endlessly kill.
This game is in eSports as far as I know. SPORT being the key word. Here you saw that in the box put 60 kg boxer vs 100 kg.? There are weight classes. Why would the games not to make too categories: low, medium and high category for example. I'm not playing and want to play with the same - we have equal chance to kill each other - roughly equal skill. Trained - moved by the machine in the middle, etc.
Very annoying when throwing beginners to play with veterans that make you like that I'm not interested and they're most likely too.
Tell me if there are shooters which are so distribute players?
