The lore hasn't changed. Male Miq'ote are still canonically very rare and you can count the number of Male Mi'qote NPCs you meet on one hand. (the Arcanist guildmaster, that one guy in Southern Thanalan, two other guys in the Fringes, and G'raha Tia... and that's it). The other male Miq'ote players running around aren't canon. Same deal as in WoW, where canonically 99% of the Blood Elves have been wiped out and there are only a few thousand still left alive. Ignore the fact that Blood Elves are the most popular Horde player race; other players aren't canon.
This has been true of every FFXIV expansion race. There aren't canonically a lot of Au Ra running around Eorzea, just as there aren't canonically thousands of Warriors of Darkness running around Norvrandt. You are the only canon player character. The closest population of Au Ra are the people of Werlyt, in Ilsabard. The Dark Knight story, you learn that Ishgardian knights had never seen Au Ra before and killed a whole tribe of them that arrived recently, thinking that they were a type of dragon or heretics that drank dragon blood. In universe, the people of Eorzea should be amazed to see you playing an expansion race, but it's too much effort on Square's part to go back and rewrite the dialogue and alter some cutscenes to account for that.
