Your friend tells you about his new job:
He sits at a computer and a bunch of nonsense symbols are shown on the screen. He has to guess which symbol comes next. At first he was really bad at it, but over time he started noticing patterns; the symbol that looks like 2 x's connected together is usually followed by the symbol that looks like a staff.
Once he started guessing accurately on a regular basis they started having him guess more symbols that follow. Now he's got the hang of it and they no longer tell him if he's right or not. He has no idea why, it's just the job they have him.
He shows you his work one day and you tell him those symbols are Chinese. He looks at you like you're an idiot and says "nah man, it's just nonsense. It does follow a pattern though: this one is next."
That is what LLM are doing.
I guess you can steal anything when you expand the definition of the word to anything you want.
You live on the internet, it would take you 5 seconds to link to the "actual definition" you are using if the word was actually used that way.
