LLMs are in the business of finding the best next token to continue the conversation in a way that models human text. That’s why it’s often likened to autocomplete. LLMs can compete with humans to the extent human tasks can be represented as a series of tokens. They can’t, by default (I think Bing and Bard can) visit a link and read it, which is why they hallucinate up reasonable looking links. They do know things insofar as it helps them find a good next token, and those things will tend be more generalized knowledge rather than specific facts and figures. I bet if you described a list of symptoms it would be pretty good at suggesting possible diagnoses, if you gave it the results of a blood test as a table it would try to say something reasonable but not know what to do.
