Observe that from each voter, X receives more points than Y (at least one more), so overall, X receives more Borda points than Y. In particular, Y cannot have the most Borda points.The Borda Count Method, the Plurality with Elimination Method, and the Plurality Method might select a Condorcet candidate, but they can also fail to honor the criterion.
