I do not mean to be rude, however generally people will refrain from platooning with players who have low game knowledge and will be a liability on the battlefield, average players have win rates around 45, you win some, you lose some, and you tie some, however below that it means you are doing something seriously wrong and need to fix it pronto. I'd suggest learning more of the game mechanics and improving yourself based off of them. Avoid blitz youtube, the current state is not good with the manufactured trash that is churned out by content factories like doodles, I'd suggest looking at the world of tanks PC guide park series. You only have around 500 battles so don't sweat it that much, I was for sure not even close to my current skill level when I started so try some of these tips out. I wish you the best of luck in your quest for improvement.
