Art isn't one thing, it's a nest hierarchy of rabbit holes.
The best, well recognized artists are hyper specific.
Those other things you're talking about require marketing, nothing else. The thing being marketed is immaterial.
IMHO you're asking this question tells me you're likely lower on the obsessiveness and openness-to-experience scale. It's not a personal failing, it's more of a personality / constitution thing.

My question though is, "Why?"
Personally I've seen more than a few friends in similar position (not already artists) exclaim their desire to take up a specific craft because they recently enjoyed a certain piece of art themselves. That's fine, that's great actually. But it's fading.
Art for art's sake is usually a compulsive and life long pursuit. Barring brain damage.

p.s. That 'brain damage' comment was supposed to be funny. Life as a creative isn't always easy. Especially if you have confounding personality aspects like high neuroticism or low conscientiousness. Here's a little less than an hour about it. If you're thinking about it it'll be more than worth your time to investigate yourself about it.
