If one gets a degree in some esoteric, non-practical area of study, then yeah it is wrong. Or at least very much incomplete advice.

Does there exist any advice where its impossible to do it wrong?

E.g. On this account, "stay hydrated" is bad advice, since if you drink 60L of water in a day you will die

Sure, of course not. But some advice is more clear than others…
