I suck at this game

Good god! I am absolutely atrocious at this game… But I absolutely love it. I have roughly 200 hours in this game and I guess you could say I have some “knowledge” of the game when it comes to the maps, loot, spawns, ammo, modding, etc… But holy sh#t do I suck at killing people. I’m currently doing punisher part 4 and this is where I truly am seeing the lack of awareness and mechanical skill, and it’s extremely frustrating. Things get worse when I come to this beautiful subreddit and watch a clip of ChadJunior as a player scav murder 5 thiCc bois with his no sight Sks… I tend to be one of those people that watches everything on YouTube, so I see a ton of content from Pestily, tweak, summit, etc. And I think it makes it worse because I feel like I can do what they do but get frustrated cuz I can’t. Meanwhile, My buddy is out hear murdering 4+ pmcs every raid on full auto. Anyways, I’m new to reddit so I have no idea why I can’t find the rant tag, so I’ll try and spark some conversation on what you guys do to try and Improve. If anything I would like to know if any of you wonderful souls share similar issues as me
