Unrelated to the paradox, there is a distinction between a definition/category statement, and a prediction about the state of the universe. There are different uncertainties involved, and different evidence that would move those probabilities for you.
If it means “by definition, any bird of this form which isn’t black isn’t a crow, it’s something else BECAUSE it’s non-black”, then the uncertainty is about whether whoever you’re talking with is using the same definition.
If it means “we never see this biological cluster of features without also having black pigment”, that’s much more empirical, and subject to observational evidence.
