Bought a new pc recently

So, I got a new pc, and I bought a few games, but not all run the best, games like ready or not run very slowly on it, even on the lowest setting. I asked my friends about it a couple days before I bought the pc, and they said it was good. I’m not sure what I need to change to make it run better, but it’s a (I’m copying this off the website) YAWYORE Gaming PC Desktop computer AMD Ryzen 5 5600GT,16GB DDR4 3200MHz,1TB M.2 NVMe PCle4.0 Gen4,550W 80PLUS PSU,WiFi,Game Design Office console,Sea View Room,Windows 11 Tower Prebuilt PC. I’m not a pc person, so if you could simplify anything for me, that’d be appreciated. Thanks, I’ll insert a video to show what it’s like. Lemme know what I need to upgrade.
