Not necessarily. Finding out you're incorrect about some fact of the world is a first step to uncovering a truth, indeed in the case of a dichotomy, being incorrect about a fact instructs you on the correct truth. So if you were shown to be wrong about fact A, you are almost always closer to a true belief, even if it simply the absence of a false one.

Also, being shown to be wrong every day does not mean shown to be wrong about the same thing. Each day you could be shown to be wrong about a different thing, and each error can lead to updates in your mental model for how the world works.

Although I love the pointless dissection over a single sentence, the phrase is ambiguous as most phrases are. So superficial would be the right word to describe most aphorisms, as being merely pointers to a more nuanced set of beliefs. Don't sweat the small stuff.
