Seems fair to call those ethnostates as well.

Edit: I asked ChatGPT "How many nations have declared themselves to be the Nation-State of a people?" earlier and got the same answer as you. I asked again just now and got "Israel is the only nation in the world that has legally declared itself the “Nation‑State of the Jewish People.”" [I didn't specify Jewish]

Can't rely on AI.

You should consider that AI is often wrong and stop using it as a source of truth.
