How do I become good at COD

To those that are absolutely cracked, sweaty, and just plain good……how? I’ve been only decent ( maybe) in the COD titles I’ve played in the last 17 years. I’ve only dropped one nuke my whole cod career back in 2010 on the original MW2. I work a 9-5 so obviously don’t have all the time in the world, I do know that sbmm is a thing but even still i consistently find myself getting shitted on more times than I like. In bo6 I’ve changed settings, done private bot lobbies to practice aiming and peaks, I’ve been in the firing range so often if they had a mastery camo I’d prolly have it unlocked already, I’ve tried to pay attention to spawn position and switches, but I just can’t seem to be Good. It seems that Winning gun fights is stressful more times than fun, everybody ping is 3, and I’m the one that’s slow. I just can’t seem to get a jump on this learning curve. How do I get good?
