How I be consistent every match?!

I do everything. Aimlabs, Range and death match. I have W crosshair placement and preaim and I also get 21 on hard bots but still I can't even pass bronze rank. Why?

I have defeated ascendant in 1v1 but why still I am in this much low elo, all aim training I do it's like it just disappears when I enter in match.

Pls help me
