Nope. That's just the apps you currently have in your library - any previously deleted ones won't show up there.
@ the OP - you're looking for purchase history. Go to the iTunes Store, and log in if you need to. Then click on your email in the upper right corner and a new screen will show up. About halfway down the new page should be a button reading Purchase History - click it. If you need more detailed instructions, check out this
apple support page.
