Rambam does also mention that a city (a 120 person city) has to have 10 batlanim, i.e. people who do nothing but sit in the beis medrash and learn all day.
Since even according to Rambam we need 10 FULL TIME learning-only Jews per 120 Jews, we today still have a long way to go to reach this ratio. We have far less full time Torah learners per 120 people. Especially considering most Jews aren’t even religious, let along learners. (And I doubt we have even close to 10 to 120 counting only religious Jews.)
