My anecdotal experience with competitive games has been that the top ~15% of players generally have a winrate >50%, with the top 1-5% usually clearing 55%, especially where some skill-indicative metric is used to do matchmaking. The fact that winrate is 50% across the board implies that they are somehow fixing matches, or (as the author states) simply banning their most skilled players.
