A fact is something that happens. If you read “theory” as “model” it makes more sense.
So evolution occurs. Our model of it is crap.
Gravity exists. But Newtons model of gravity only works for human things approximately human size and speed. When it gets too big and fast we need Einstein’s model (general relativity) to explain things, if it gets too small we need quantum gravity.
Or put differently: it is a fact that I wrote these words. If you tried to describe my words with a theory/model, and it predicted which words I would write next, then you have a decent theory/model.
We have tons of evidence that it happened but our models for explaining and predicting it are bad at consistently and reliably explaining everything we’ve already seen, and each new discovery seems to break those models even more.
The theory is the model trying to explain how it works. The fact, though, is that we have evidence showing that it did happen, even if we don’t have a unified theory of how it happened.
Imagine a car crash site, where the cars have definitely crashed, but everyone has different debates about what caused the crash. Imagine further that the specifics of any person’s explanation has a few inconsistencies with what we see. So we’d have the fact that a car crash happened, but lousy theories explaining how it happened.
I think it’s because a proper theory needs a postulation of the cause of the phenomenon. We don’t have a single source on the cause of gravity or physical mechanism of evolution.
Me either

I hope this helps
Thank you for this very clear explanation
