In normal games, My team has 200 wins while the enemy team has over 2 thousand ???

I've only been playing a few weeks and talking with some other new friends we were wondering why we keep getting owned so hard by players that seem pretty experienced

I'm only level 20 with like 70 wins and after looking at our enemies after games they have 1 thousand wins each!

A typical game, my teams total collective wins are about 200, while the other teams total collective wins are 2 thousand! Thats a huge gap of experience, and it shows, the games are just not fun. No matter what I do or try to defend my teammates they just keep getting rekt. It even happens all the time when I get matched by myself

It seems like its because the experienced players are grouping with smurf accounts or their new friends, which causes them to be matched against 5 new players, meanwhile 2 of them are really experienced.

Here is a picture that shows the win differences

I dont understand why this is the way it is I mean I understand one game in a while but lately its like 3 out of 4 games are unbalanced like this, my teammates are all noobs while the enemies have multiple players who have been playing 1-2 years

Does the game have like virtually no matchmaking system at all for non ranked games? I dont like the pressure from always worrying about my rank, I like to play normal games but this system just seems like it matches anybody with anybody without a care in the world which to me shows lazy dev work and not any effort at all for offering newer players a good experience...
