Why do so many people only play NBA 2K, Madden, or CoD?

I don't mind people's gaming tastes, it's absolutely okay for them to play these types of games. I'm just curious as to why everyone I encounter in real life ONLY play these games??? Like the combo I always see in real life is teenager/adults: Play 2K, Madden, CoD, and maybe Fortnite/GTA5 on the side. Smaller kids: Roblox and Minecraft. That's it. Again, I have no issue with this but it's so strange to me how I'm 17 turning 18 very soon and yet I somehow feel like I'm behind with the times of what people like to play these days 😭 Like you don't fw no Mario, no Spider-man, no GoW, no nothing??? Like it's genuinely hard for me to find ppl with a common interest in video games with me unless I purposely seek them out in specific groups.
