Sports isn’t something you just come to like, it’s something you actually grow into from time. It’s a good thing you don’t have a time to grow into it as, you can actually start liking a sport from a much later age but before that fully materializes, their have to be some level of interest towards this new thing you want to be involved with. You start by understanding how the game is played before getting to know some of its key players and you keep up with the sport, be a fan and be active at it.
Yes, it's very true, with time you can also learn many things, although I would say that to learn a sport well and poorly you have to like it and go into detail, see each thing and what doesn't seem interesting to you, start to review each player, each athlete in the sport, that is essential, as well as start to watch the sport and see what the narrators think , sometimes that helps a lot because some narrators have the same concept as you as a fan.
