There are 2 parts. At the center is the singularity. Theoretically, this is an infinitely small point of infinite density. This has no volume. Around this is the event horizon. This has volume, and is what we refer to as a black hole. Theoretically, you could have a black hole without a singularity, you just need an area dense enough that light can’t escape.

It depends what you mean by big. Are you talking mass or volume?

If I remember correctly supermassive black holes do consume space and can be quite large. They can also be much less dense than neutron stars, let alone stellar black holes.

Beyond the event horizon is just insane math and theory

I came to ask something similar, but far less eloquent. So, if you don’t mind, I’m just going to piggyback on your comment.
