How to make irl friends in your 20s?

Same as the title
I am 22 and in college I'll say i have friends but we are not like close . Our friendship just stay in classrooms and college after that no plans , nothing and calls only occasionally just for classes purposes. They all have their different friend circle to hang out with. But for me , all the close friends i had are now scattered around the country and now has new people.
I don't have time to join or regularly attend any clubs or activities.
It's just so depressing to not have friends or people to hang out with, to talk with.
