Ok but then the theory of black holes are wrong because this isn’t dense at all.

Only the infinitesimally small singularity that is in the future of all objects inside the event horizon is supposed to be very dense. The space inside the event horizon is supposed to be normal-ish

If such a singularity exists at all. The thing we "observe" about black holes is the event horizon. It could be that space inside a black hole is just regular space.

Yep! Generally speaking singularities only appear because the math is deficient in some way. Other areas of physics successfully got rid of unphysical singularities by employing better math, it's just that we don't know how to fix this aspect of general relativity (maybe quantum gravity will?)
