Legend
I guess I at least put half-orcs on the "weird" category and gnomes too. I've never had either in one of my games.It isn't just human vs. non-human IMO though, it is "typical" vs. "exotic" (for lack of better terms).
If you look at the site you mentioned, over 70% of the races are typical (human, elf, dwarf, half-elf, halfling, gnome, or half-orc), for the 5E crowd you could argue that dragonborn and tiefling should be included, but I'm not for this case.
So, if all other races would be 30% or less in total, I would think that would be a bit rare, or definitely uncommon. shrug
Personally I thought the "normal" races where the Tolkien classics: human, elf, dwarf, halfling
