It means that after you had downloaded the youtube videos offline on your smartphone which you wanted to watch even if you don’t have an internet connection then refreshing thumbnails of downloaded videos means that after every 29-30 days youtube download the thumbnails from the videos who had changed their video thumbnail that you had downloaded offline.
