hardstuck by trolls

I am trying to get elo and maybe stop playing with bad players but it's seems impossible playing solo, yesterday I played 4 Dust2(worst map) and all the matches I had some kind of troll, I won the pistol round solo doing highlight and they throw second round to bad guns lol

If you think I am crying see these videos of 2 matches(3 trolls): https://www.youtube.com/watch?v=blpoEOkitCc&ab_channel=ShtimsCS2

What does it matter if I train my aim, know the utilities and try to play my best if my matches are like this XD
