What they are trying to say: One cannot taxonomically group every animal we consider fish without also including all the mammals and i think even reptiles and birds. that’s because there are multiple taxonomic branches of fish that split off of the trunk before our ancestors started to walk on land, and not all of the fish in our branch decided to go on land, and continued their own branch. therefore yes: whales are fish and so are you. what does this mean? ¯\_(ツ)_/¯
it is technically correct which is, of course, the best kind of correct.
After this conversation, I wish I was.
