a black hole is a small universe, inside a large universe

Maybe, maybe not.

Have you ever had a pair of binoculars that you turned around and looked through the large lens to the small then whatever was the scene beyond. That is all there is to the small universe that might exist within the large. You would be talking relative difference from here to there, not real difference this end and that end. That end would have this end the small universe within the large universe. An 'Alice In Wonderland' / 'Through The Looking Glass' kind of micro-macro / macro-micro kind of reversal of look and physics. The other end of a wormhole, maybe. A whole lot (infinities) of wormholes to a whole lot (infinities) of universes, maybe. A specie of Multiverse multi-dimensionality.

If a few solar masses will create a neutron star, and adding a few more solar masses, say 10, will produce a BH, then what reasoning suggests this 10 will suddenly produce 10 zillion more?

But since nothing can, in principle, go beyond the Universe, and nothing can go beyond the EH from the inside out, then there is that similarity.
