No that is not true. It just means remove all files including those that don't belong to you recursively. What you need is a secure erase. Put the files you want securely erased into the trash, select the trash can, go to finder, select secure empty trash

Thanks for that, may I ask a further question please so that I can give my mac to someone else... If I have deleted photo's by using "move trash" and done "Empty i-Photo Trash" also deleted files using "move to trash" a but not "secure empty trash", how can I be certain all of the photos and files are not recoverable? Is the "Disk Utility" - "Erase free Space - 35 times" the best way to do that?

If you are going to give your iMac to someone else, unless you transfer the licenses for any software you added you need to startup holding the Command and R keys, then do an erase and reinstall of Mac OS X 10.7.5. That will erase all content of the hard drive and then reinstall Lion. The machine will be as from the factory then.
