Ymir seems to be a valuable asset since she referred to herself as a "goddess", and the Talking Titan bowed to Ilse mistaking her for Ymir. Marcel, on the other hand, was just a child soldier, little more than a tool for the Hometowner's goals, so they surely wouldn't bother to sacrifice Ymir in order to save him. Ymir guessed that the Hometowners planned to feed her to another warrior, and assuming she has some kind of power they want to steal, that warrior would be some high ranking dude like Zeke, his hypothetical superior or maybe the king of the Hometown; but certainly not an irrelevant pawn like Marcel. Plus it wouldn't make sense that they send him back to Shiganshina and risk getting him killed and losing Ymir's power forever.
