Are people with hobbies just rich or something?

Because how can they just afford so much of it or buy the newest/recent thing of their favorite hobby?
Like the newest games, newest album, Trading cards. etc

Like i can barely afford my K-Pop hobby! I’m not from Korea so Albums and stuff are so expensive. And my favorite group has like collectible digital trading cards on an app they made and it’s pretty expensive.
