Yep, it technically does, but one of the players can "decline" to start a fight by discarding one, two, or three cards from his/her hand. Since their draw pile is out of cards and they can't replenish their hand, the game then ends.
Only the player who is due to start the next fight can decline to start the fight and discard. If you just won a fight but now have only one card in hand (and obviously no deck as you refresh) then you're going to have to play on.
