The point is that neither the model nor the sampler algorithm can possibly have “confidence” in its behaviour or the system’s collective behaviour.
If I put a weight on one side of a die, and I roll it, the die is not more confident that it will land on that side than it would be otherwise, because dice do not have the ability to be confident. Asserting otherwise shows a fundamental misunderstanding of what a die is.
The same is true for LLMs.
