No it isn't.

Realistically the opposite is true in practice and LLMs are really non-deterministic beyond simplistic experiments such as this in useful activities in production. Even with hacks such as "setting temp=0" (which no-one seriously does) to "achieve determinism", was one of the most common misconceptions ever propagated by "AI engineers".

So using tiny slop experiments aren't really useful as a "strong counter-example". In fact this is a very weak one.
