Remember each category (Music, Books, Movies, TV Shows, etc) is listed separately. And iOS apps don't even show total space used in iTunes. There's also the Album artwork folder and iTunes database files.

All iTunes content is stored in the music folder, which I know is somewhat misleading. This includes any movies you've purchased and downloaded from iTunes, and a couple of those would account for the 10GB difference.
