We can't see what happens inside, that's true. But the fact that our physical models of how black holes "work" produce a description of an object that behaves externally in the way that
observed black holes work is a good indication that the theory is a reasonable approximation to the truth. Just as we can't see inside an atomic nucleus, but external observation allows us to be pretty confident of what's in there.
