Those are just numbers of the overall chars in game you took from a third party sites, they don’t indicate anything, because with them we cant see the difference from the alts and the main chars on which someone is active at, nor we can see the activity on each of the factions at the endgame content, and the numbers there aren’t nice and are far from balanced if you look at the any aspect from the m+ leaderboards, rated PvP ones to the raiding guilds on the both sides.
Its Blizzard fault how it isn’t, with the way how it managed the game and designed it allowed the imbalance to happen. Horde was more favored faction by the devs since the Wotlk and the faction imbalance started to be more noticeable with the Cataclysm, at the point where more and more players and guilds started playing on the horde side and the alliance ones switching to it.
The racials might be in balance now but the damage at this point has already been done in the years when the horde ones were better.
Your ignorance is now showing, and I do play at the endgame and have more raiding achievements than you do have. But the thing is that with having the most competitive players playing at the horde side everything is harder to organize and do at the alliance side from finding groups to play with to the recruitments of the players for the progression guilds at the endgame.
