Yes, SQL, HTML, CSS (not on this list apparently), XML, JSON, YAML and a couple others are all declarative 'programming' languages. I don't know if there's a formal definition of what is and isn't a programming language tbh, but either way I wouldn't consider them lesser for whichever reason.

That said, I think SQL, CSS and maybe HTML are the only ones that are a league of their own, that is, you could get a job as a pure CSS or SQL programmer.
