Poppa, that quote tells us that anyone make aspire to kesser Torah, and trust in the havtocho of divine providence. It does not indicate that an individual or community should sit and learn with a hand stuck out.
Quite the contrary, it is precisely saying the community must support them, as well as relieve them of sharing all societal burdens, like shevet levi.
GAW: I disagree with you about the reading. Parak me’al tzavaro means they decide not to engage in productive activity, and rely on the community like the leviim, as I noted.
