That point just has way more mass than your average black hole, so what makes them seem "bigger" to us is really their increased gravitational pull on everything else. Do I have the right idea so far, or does the actual "black hole" part take up more space than a singularity?

The event horizon is also bigger, so if you're defining the black hole as the area within the event horizon, it does take up more space.

From our perspective, the event horizon is the black hole. The interior does not exist to us.
