After 70h of CSGO i still cant calibrate, can someone help me please ?

i only won 7 out of 10 matches and im about to quit this game if the situation will not change. After maybe 40 competitive games i cant win. I know i'm bad but half of my matches when i'm about to win im getting kicked last round or my team starts to kill each other and ties 15-15. WTF is wrong with this game? It's not like im that bad either. I play with gold 3 or gold 4 players and im never last the scoreboard. What's even more weird is that when after some deathmatches i went into competitve (same day i bought game) on the first match i got paired with legendary eagles and master guardians (they were very helpful and forgiving after i fed every round) and i won like 7/10 matches. but then after some time of cooldown i started getting paired with gold players and holy shit the people playing there are so stupid. Everyone is as bad as me ( im not moving down in rank since then ) but thinking they are pros or something and kicking people for anything. muting everyone when match starts is obligatory now for me. And it's not like im new to player toxicity, i played dota2 for 10 thousand hours (yes 10k) and i have seen some shit, but this is just too much for me, the idea that you could kick a player in the middle of match is absurd for me, like it gets abused so much.

What makes gold players so toxic in this game? Dota is much more emotional game and you need so much more time and effort investment in it yet it doesnt get as toxic.

Please tell me that when i maybe finally calibrate people would be normal again, not russians who kick people when they see you dont speak russian etc...
