No, everyone is ranked by a hidden Elo value. Although the people you are playing might be 50 ranks higher than you your Elo values are probably really close.
The levelling system has no bearing on who you meet in auto match.
I am just wondering how that can be. I'm not that great a player, I lose pretty much half the time if not more. And I feel I get outplayed pretty badly sometimes, yet you'd have me believe my opponent is of equal skill/elo?
