Most fish are not jawless. There is a small group of very primitive fish called Jawless fish (Agnatha). However, they make up a very small proportion (<1%) of the fish species on earth. Jawless fish are things like lamprey and hagfish. All other fish, like trout, salmon, tuna, sharks, rays, cichlids, goldfish, etc, etc, have jaws.
