I'll reword it this way: the more you know, the less you have to rely on experts, or at least the degree decreases. But the practical angle of this is that one will still have to heavily rely on experts until they reach a non-trivial point in their education/study of the topic. It's not realistic that the average person master every controversial topic in order to vote fully informed.
This does not fly with most complex disciplines where it takes decades to become proficient.
But relying VS not-relying on experts is a false dichotomy. You can choose experts to trust, as rationally as possible.
