Too much playing, not enough learning. Doesn't matter how many games you play if you keep thinking your teammates are the problem. Like I am not very good at this game, but I have ranked two accounts to gold this season playing solo. No matter what your rank is, its a reflection of skill over a period of time. The good news is it can change game to game. You have to focus on the game in front of you and try your best to win. Learn from losses and from wins. Become aware of your mistakes and learn from them. The more you learn and more consistent you become the higher rank you will be. Maybe one day if you get good enough you will rise to pro level. Only problem is, a very small population is that good at the game and it takes a lot of work.
