These are two quite different things. We group them under one name, 'facts', but that is just a convention.
There's a reason we use the same word for both of them. They have a lot in common, for example being extremely objective in practice.

Either someone has a suggestion for a new kind of fact, which we can then evaluate, or else the subject is barren. The mere fact that "we've not ruled out that there might exist more things we would choose to apply the word 'fact' to" is very weak evidence. We've not ruled out china teacups in solar orbit, either, but we don't spend time discussing them.
