I’m not clear what you mean by “know.” If you mean “the information is in the model” then I mostly agree, distributional information is represented somewhere. But if you mean that a model can actually access this information in a meaningful and accurate way—say, to state its confidence level—I don’t think that’s true. There is a stochastic process sampling from those distributions, but can the process introspect? That would be a very surprising capability.
