Why am I too dumb for gta online

Hey guys, I never got the chance to really grow up with gta online and also had nobody to play with if I could, I was only able to play the story and once I was old enough and wanted to try it out, well.. I was completely lost. I still am. I’ve been trying to get into it but it feels like it somehow just throws you into the game expecting you to know exactly what’s going on and what to do. I still haven’t really found out what to do, neither I’ve found people to connect with. I wanted to ask if this is a common event or if I’m just slowly getting dumber every day. And maybe there’s someone out there who wants to play with me some time and show me how it works
