I think that what Ichibei said could have two meanings: a. The HUMANS won't be able to defeat Yhwach, meaning they would die in battle for whatever reason. They might not have (enough) power, they might suffocate due to a reishi overdose, yadda, yadda. Perhaps he talks about Chad and Inoue, since they are some (odd) humans. Ichigo is a little...well, an Ichigo. Having Ichigo and Co. going up is like having a human shield. Sacrifices need to be made for peace to build...

b. Perhaps Yhwach can't be defeated/killed as he is somehow tied to the human world. Killing him somehow, if even possible, would somehow make the human world vanish. Although it is still unclear what Yhwach meant with this whole father thing, I think it was pretty interesting that the Soul King seemed to lack arms and like a proper facial expression. It reminded me a bit of when Yhwach's history was revealed. What if the Soul King is that what Yhwach gave to humans but then to all three/four worlds?

Silly me.
