Sounds like you think I'm trying to argue that most people on earth in 2022 are still nomads? Really, this was about anthropological (and, unstated, evolutionary) averages. Nomad's evolutionary and genetic inheritance is our own, very largely. There hasn't been enough time since agriculture came, enough generations, for widespread genetic change.
Anthropology studies past societies as much as modern ones, although the evidence is thinner.
