You can see the same thing on a hard disk, and the discrepancy will become worse if you have many files or a very large disk.

What happens is that the disk space is allocated into addressable 'chunks' of a certain size (2^32 such 'chunks', with FAT32). This means that if the file does not evenly divide by this size, its final few bytes will be occupying MORE space than the actual length of the file.

This is also true with very small files -- the file is written into, and then occupies, an entire 'chunk' that may be (relatively) much larger than the file length.
