If three of my friends that have never played basketball take a shot and they all miss, that doesn't say anything about my ability to make a shot. Obviously, my friends are inexperienced with basketball. There is nothing wrong with that, but it's not a fair or just argument to tell people who do have experience that "your success not a true one-shot because other, inexperienced people, failed".
You appear to be extending the definition of "one-shot" to "an LLM should be able to accomplish anything no matter how poorly it was prompted", which is, I hope you can agree, not very reasonable. It's certainly not something I would be arguing in favor of.
