Dinosaurs were not reptiles. They were warm blooded, and birds descended from them.

They always use mammals for that kind of comparison. Show me a reptile with that kind of muscle/fat composition.

Birds are reptiles. Commonly, we wouldn’t say so, but they’re in the same clade. The avians are closer related to the crocadilians than the crocs are to other reptiles like the squamates - lizards and snakes.

Also people are fish. You can’t evolve out of your clade.

Hank Green went off about this recently. “Fish” just has no scientific meaning, and there are fish tetrapods.
I don’t necessarily disagree, but ultimately there is a problem in classifying “fish” in the modern scientific taxonomy system - it has no good phylum to fit in as its a term that’s a bit more broad than that, but not broad enough to make for a kingdom.

Birds? You mean the last remaining dinosaurs?
