well, it depends on the way you interpret your question.
1. if you're asking if this is copyrighted so that you can edit/make this again, i'd doubt it, just credit them

2. if you're asking if this is committing copyright infringement on palworld and pokemon, then no, as those are different games and you could say this is just inspiration

im no copyright expert but this should clear it up for you

Gotta love a mod that is borderline copyright infringement of borderline copyright infringement (I do like Palworld, I just think this is funny)

is you speak english? i am maybe sure not
