Regarding "fish" Old classification relied on "phenotype" characteristics. And yes lamprey, a shark or a cod has little in common genetically. But they still share some common traits that distinguishes them considerably from whales, sea lions and seals. I still think the term "fish" is useful, and modern classifications rely more on genetics so I would say that the argument is semi void.

They didn't say that fish wasn't a useful concept, they said that the more you delve into the facts, the less certain you can be that it has a definite meaning that can be pinned down scientifically.
People think the science agrees with them that the world can be divided into fish and not fish, but that's absolutely not what the science is saying, and their understanding is superficial.
Similarly, the terms male and female are generally quite useful, but the people who think that there's some kind of scientific and absolute binary distinction between them are just incorrect, and their understanding is superficial.

I mean there are lots of differences between male and female.

In the same way, there are lots of differences between fish and non fish.
