The female gamer thing is not as much of an issue for me that I've seen, although I have seen it occur in many other games. Also playing with randoms pays off sometimes.
An example was last night when I logged on and realised no one was really playing and had jumped through 2 or 3 skirmishes, so I posted in the general chat some off hand comment about no one playing.
Within seconds I got an invite to a 5 stack composed of 2 Koreans, 2 Singaporeans and 1 Japanese player (and suddenly me as a representative for Australia lol). However the group I joined was 60% female and the gender had no issue. We didn't lose a game and played till 2am. Sure the skill varied, their pings were obviously amazingly low (single digits) while I was on 200 - 250 so I couldn't really play any DPS and just went tank for most of the time and was usually getting gold eliminations with Reinhardt / Winston / Zarya picks. (Picks were game knowldege and decision making is more important than anything else).
The stats weren't interesting to me it was more that in Asian countries, gender doesn't really play into tropes of whether you should or should not be expected to pay games.
