The beginning of the universe and black holes have in common the singularity if you think about it naively. Besides that there is not much of a connection. And I think most physicist don't believe there are real singularities in black holes or at the beginning of the universe but quantum mechanics, quantization of space and time or something else kicks in and prevents the singularity.

And there is no(t much) doubt that very massive dark objects are out there, we can observe them indirectly. So even if the classical black hole creation process turns out to be not possible, there are still objects out there that a very much like classical black holes.
