Context is what matters in this case. Gilgamesh has pretty much just been there in prior FF games. Here he's introduced as a duelist that's challenging people and taking their weapons.

It'd be one thing if he had been introduced as this villain that randomly attacks groups of adventurers or soldiers and steals their weapons. Instead he's challenging people to one-on-one fights and taking their weapons. It stands to reason that the player character, being a cut above the average adventurer, blessed with the power of the echo and so on would single-handedly end Gilgamesh's pseudo-undefeated streak. The set up is definitely there.
