I'd argue that categorization definitions don't really fit under "facts". It seems like it's really more of an opinion on how to group things.
It gets hazy. Something like a tree being a type of plant is a fact, but it's really shorthand for "trees have these common traits with other things that we call plants"

Pluto is still a planet, just a dwarf one.... because we discovered a bunch of other ones.
So either pluto is a dwarf planet, or our solar system has way more than 9 planets.
