I do agree humans don't have a world model. It is really more than that. We exist in the world. We don't need a world model because we exist in the world.

It is like saying a fish has a water model. It makes no sense when the fish existence is intertwined with water.

That is not to say that a computer that has a model of the world would not most likely be extremely useful vs something like the LLM that has none. The world model would be the best we could do to create a machine that simulates being in the world.
