For most people who are not doing their day to day jobs it's just a prompt of their idea roughly sketched out and a miracle happens - LLM fills in the blanks. Every time it's different but it works, sometimes even better than initially expected. That's why the addiction and gambling. Gambling is a lot of things, not only flashing lights or play sounds. Some people claim prediction markets isn't gambling either, though that doesn't change the fact.
How is this different from hiring a designer, telling them "make me a website" and then waiting to see if they resolve the uncertainty into something you like or not?
I tell LLMs what to do in pretty high detail, and they do it. With LLMs I have much less variance than with coworkers.
