You don't know what you don't know, as the saying goes.
Exactly.
I was enrolling some camera classes last week, and I always ask what people like to take pictures of, and I'm always surprised when someone says one thing.

OK, some have bought a camera just to take pics of the grand kids, but to not even think about taking a pictures of anything else seems odd.

And if it is something as seemingly narrow as the grand kids, what about when you want a portrait, as opposed to pics when they are running around. :shrug: And then what if you want to show them in front of a lovely landscape or sunset. :shrug: That seemingly simple subject now requires a few more skills if you want to get good pics.
Sometimes students can be inspired by seeing something they have never considered or even seen before. I was describing some options for a difficult lighting situation of an unlit statue in front of a floodlit building, and mentioned cutting and pasting different exposed elements, HDR, and light painting. Most had not heard of light painting, so we went and had a look at some examples on the internet, and I described how some of the effects had been achieved. One of the students was very excited about the idea, and texted me the next day saying that she had her son helping her, and she was giving it a go. The point is she didn't even know about the technique, and if you go into anything, but Photography in particular, which can be a huge varied hobby, with a very blinkered view, you could be missing out on quite a lot. :shrug:
Learn to use the camera first, and then try and learn the additional skills to get the most of specific subjects you try.

It's all knowledge that will will hopefully make you a better photographer.
I take pics of whatever I feel inspired to try. If I don't like something after trying it, then at least I know I don't like it.
