I would say the best way to make friends would be to go to a club which is based on something you enjoy, it doesn't necessarily have to be sports it could be a book club too. Go to local hangout spots in your neighbourhood and try to talk to other people with small talk, finding out their interests,etc.
Alternatively, there are quite a lot of groups on social media (Facebook, reddit are the 2 that come to mind) which you could join. Where they either go out to watch the game, play games, read, etc. All depends on what group you have joined really. You could also chat with online people on discord, finding a random group with a theme you are interested in, and joining it.
Of course, these ideas should not come at the cost of your health. If you find them alarming and not your type of crowd, make sure to put you safety first and leave.
