Absolute Elo ratings have no meaning. The system is set up so that differences between Elo ratings are predictive of the outcome of a game. There's nothing anchoring the overall scale, though, and you can add in an arbitrary constant to every player's Elo without changing any of the predictions about who will win a given game.
