playlist that actually just teaches you fundamental mechanical skill?

I know there’s tons to choose from and that’s my problem, is there one that’s meant for bronze benchmark players to just grind till we have better fundamentals?

I feel like my aim is so hit or miss sometimes and I do ok in fps’s but I’d like to never die because my aim is bad, I’m totally fine with my dumb choices and my stupid plays getting me killed, but if I’m positioned correctly and have the jump on an enemy, I’m tired of feeling like my aim is so ass and I should’ve won a battle easily but die due to poor aim. I was thinking about doing benchmarks as practice but it feels like those are more to test you than to train you. Is there a playlist that’s like purely going to train my skills as I play it for months?
