I’ve always thought of the definition of “expert” as reliably knowing the difference between what is known, what is speculated but unproven, and what is unknown. People claim expertise in all sorts of things that they aren’t experts in. But true experts should not be wrong. They should qualify levels of certainty. This definition certainly works in the sciences.
In reality few humans are true experts on every topic they open their mouth on. A high school teacher in science is hardly a true expert in every single thing they teach.
