How do we meet people with common interests?

I'm 21 and need friends but I don't really know how to find people with common interests even more so when my main special interest is WWE so it's kinda hard to find people into Wrestling as it's not as popular as it once was.

I'm also into Gaming and Film but they're not really topics I can hold a conversation with for very long as it all depends on if people have played a specific game/watched a specific movie and if they have the same console or not which is a bit of a struggle when it comes to continuously talking about them.

Tried the MeetUp App but there aren't any groups in my local area so it's kinda a bust for me so any other advice would be greatly appreciated

Many Regards
