There's no reason to think those cases will go any differently. As far as I know, the ruling would have to be appealed at this point. I am only commenting to say that there is reason to think this is true:
> But isn't it already known and admitted (and allowed?)
You seemed to be confused about why this person believed that:
> No, and I don't see where you got that from.
And I wrote a comment intended to dispel your confusion. The above commenter thought that it was allowed because a judge said it was allowed; that can be appealed but that's the reason someone thinks it's allowed.

Trial court rulings aren't binding precedent even on the same court in different cases, so its quite possible that different cases at the trial level can reach different conclusions on fair use on fairly similar facts, given the lack of appellate precedent directly on point with AI training.
A single verdict about a specific case (13 authors vs META) does not mean it's legal for companies to steal IP from other companies which has evidently been going on for some years now.
Those other companies have lawyers powerful enough to change jurisdiction in many countries in order to "protect their IP".
There hasn't been any trials yet about the millions of copyrighted books, movies and other content they evidently used.
