Sort by status/importance

Sorry if this info is available somewhere (I"m sure it is but I could not find it searching the forum). Can someone tell me the difference between sorting by status and importance?

Status indicates how well you know a specific term. You control the Status yourself either manually or by or by indicating “Got it!” during flashcard sessions. Importance is determined by the frequency with which a specific term occurs in the content in our Library and gives you an indication of the importance of that term in the language.
