Seems so. Wikipedia tells there are seven classes of vertebrates:
Agnatha (jawless fishes, paraphyletic)
Chondrichthyes (cartilaginous fishes)
Osteichthyes (bony fishes, paraphyletic)
Amphibia (amphibians)
Reptilia (reptiles, paraphyletic)
Aves (birds)
Mammalia (mammals)
So yes, fishes is the same thing as vertebrates.
Probably because if you were a vertebrate living in the sea, you needed some sort of gills and fins and such. And those are what makes people assume something is a “fish”.
Is fish just another name for vertebrates ?
Nah. You could have a fish that evolved out of having a spine (see: Chuck Schumer) but you can’t evolve out of a clade.
