They haven't said that at any point; in fact, I can't even remember them actually mentioning nomads as a proper thing anywhere in the show either.

A nomad is a term reserved for people who specifically don't set down roots and set up shop anywhere but instead travel constantly, only stopping in a location for a short while before they move on. A small village which has settled in and become a constant home that is mostly self sufficient cannot be called nomads because what they do goes against the meaning of the word itself. They would just be called villagers, and everyone would know they live outside the Kingdom anyway because the kingdom has been shown to basically be an extremely large city with a few forests within its borders. Anyone mention "I'm from such-and-such village" would instantly be recognised as someone from outside the kingdoms.

To call them nomads is a misnomer.
