Is it zero?
Or is it 20% (which happens to be about the same likelihood as making a draw to a flush on the flop in hold'em)?
If the 1640 player held the outcome in his hands, he, being the better player, would always win. Similarly, if the only resource the 1400 player has is his own ability, then he, being the worse player, would always lose, as his only resource is inferior to that of his opponent. There is nothing in your view of the game that can account for why the worse player sometimes wins. Nor can you account for why you can't determine ahead of time which player will win any given game.
Thus, you can either believe that there is no chance element in chess competitions, or you can accept the Elo rating system as meaningful, but you can't have both, since the theory of the Elo system is grounded in expectation and explicitly claims that the outcome of any particular game is a probabilistic function of the players' relative abilities.
