Some of them, like the standard ChatGPT prompt, have been repeatedly retrieved by many people over long time periods, using very different methods. We can be pretty sure they are not hallucinations. And correctly retrieving these prompts lends credence to the claim that you were successful at extracting the other prompts, even though it's not conclusive proof.
Of course OpenAI might have a completely different prompt and do some post-filtering of the ML output to replace any mention of it with a more innocent one. But that filter would have to be pretty advanced, since many prompt extraction techniques ask for the prompt a couple tokens at a time.
