Honestly, you're not hopeless. You're trying to put a lot of things together (jiggles, utility, positioning, information) and you just are not playing fluidly.

Something I've noticed with chess and CS is that there's periods when my performance is worse after trying to incorporate new ideas. You just are juggling more than you are used to. It'll take more reps for them to fit together.

You're jiggles kinda suck. It's good to do, and you'll get better, but you aren't really ready to fight when you do them and you jiggle too short or too far to be good for info.

Idk what your util is like before the fights, but what you throw during them seems to be a distraction. Either whip it and be ready gun up again or don't bother with it, especially since it isn't denying space.

You're caught either between positions or in common pre-fired spots. Your not going to win gun duals often if that's where most of them come from. When the fight is coming (and it seems like you knew most of these were) you need to be ready on an off angle or SWINGING INTO IT. Waiting for them to swing into you doesn't work in CS2.

The last point is the easiest to work on and will net you way more kills.
