There is no definitive statement on what is Fair Use... not for Youtube or anything. The general guideline is that as long as the media (image or video) is being used to to promote the topic it can use the Fair use claim. However, if the owner of the source image objects, it usually immediately loses its Fair use rationale. Text is more often covered by some other license, like Gnu or CC, etc.

Just to be clear... unless a Youtube video is issued in an official channel or original content, it is probably not being used with any permission.
