No, you really can’t claim definitive knowledge about singularities based on our current models. The rules—as understood through general relativity and quantum mechanics—change drastically at the scale of a singularity. No amount of observing shadows of a singularity conforming to predictions changes the ignorance regarding the interior of the singularity. Given that these conditions are fundamentally outside of our current observational capabilities and that existing theories are known to break down under such extreme conditions, it is presumptuous to apply conventional physical models developed for ‘normal’ spacetime. Until we have a unified theory of quantum gravity that is experimentally validated, any claims about the behavior within singularities remain speculative and should be treated with appropriate skepticism. Just because it appears from our reference frame that a black hole compresses to a point and a white hole emits from a point, does not mean that is the physical effect occurring from within the singularity. When dealing with infinite, the rules change. For all we know, beyond the event horizon, the environment could be as fantastical as a land made of ice cream and lollipops—where everything around is sweet and edible. Doubt that? Send a probe into the nearest black hole and somehow retrieve it. Also, locate and observe a white hole, and develop an engine with infinite thrust that can approach it. I'm sure there will be enough observational data then to make finite claims. Good luck!
