I think it's true that surveys like this will skew towards more serious/dedicated practitioners, but in addition to professionals, the Rust community has also at various times attracted people who were excited about bleeding-edge things, or PLT/type-theory people, etc., and I think this survey probably does show a shift in the user base towards work-a-day users and away from these other groups.

(Or more succinctly: the absolute numbers are probably meaningless, but the trends are maybe worth watching.)
