"du" walks the filesystem tree by manually walking the directory structure. It counts all of the dynamically-allocated blocks associated with the files it finds, but it does not ever find files which are open but deleted, nor does it find filesystem tables such as the inode table --- in both of those cases, the data is simply not in the directory tree. You also need to be careful to use "du -x" to measure filesystem occupancy, as otherwise du will quite happily recurse from one filesystem into another. "df" simply returns the filesystem's internal free space counts, which include absolutely everything that has been dynamically allocated.
