One of the things which make CS:GO unique is it's replay-ability value... It's a remake of the Source engine, which in turn was adapted from the original half-life engine of "Counter-Strike".
In turn, the skill-cap is very unique in that same regard... Some people are good at it, some people are bad at it -- but in the end the only thing that matters is having fun and enjoying CS with your friends. :D
Who cares it took your four thousand hours to reach LE? As long as you had fun getting there, right? :D
