Are black holes just super-dense cores created from the star core collapsing in on itself?
Pretty much.
You're exactly right when you replace "super-dense" with "infinitely dense," as you can see that the singularity's density is infinite because its volume is almost zero.

Indeed, black holes are created when massive stars collapse due to gravity, leaving behind an extremely dense core.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
