LLMs are not deterministic.
I'd argue over the short term humans are more deterministic. I ask a human the same question multiple times and I get the same answer. I ask an LLM and each answer could be very different depending on its "temperature".
If you ask human the same question repeatedly, you'll get different answers. I think that at third you'll get "I already answered that" etc.
