That's what I think it is by the amount of leagues, teams (or in this case individuals for relevant sports), and fan followings that exist, both domestically and internationally.
Basketball is definitely growing quite fast, in Europe it's becoming a lot more popular than it ever was, I definitely see Basketball becoming the top 3 sport in the world in the future, I don't see football ever losing it's #1 spot. Same is happening with basketball in East Asian countries. I think with a combination of it growing in Europe + East Asia it could overtake cricket in the future too.
this might be the best list, but i dunno about golf fam
