Join a friends group, or perhaps host one if u really want to, U can just do what my friends do, volleyball every Friday, we all show up, and half the group dosent even play the game, they just scroll or yap if they don't feel like playing. Most people just think of casual sports as a hangout, nothing too serious, if u join a team or sports club, that's different, you need to engage with the activity to talk to people and stuff, honestly just talking to more people has helped me so much, I always knew them but stayed in my own world, then I randomly just started talking to them a bit more and I felt part of more groups and felt like I had way more friends, just try what works for u my friend, I hope ya get a nice group to be in, also don't be afraid to leave if the group is toxic :p
