> Ambiguity: [...] Different or non-deterministic models will return highly variance results.

Yes, and thanks. That was my intended point - but you point out a better example. Slightly different prompts may also produce highly varied responses.

(My subsequent comments on ambiguous models was in case I was misinterpreting the comment I was replying to. I also generally think of ambiguity as a property of input. Either way, ambiguity is not the same as non-deterministic.)
