If I delete something from a Memory card of a digital camera, is it really lost and cannot be restored ?

No. There are lots of programs such as Data Recovery Wizard that can easily restore deleted files.

If you want to make sure that the files are unrecoverable, use an eraser that overwrites the files over again.

If the card has been re-used since the deletion took place there is a good chance the pics are gone for ever, if not they can be recovered (sorta)....google for a solution, there is free/shareware software available to do this.

Great !

cers, check this out for some good freeware options. Personally, I use PC Inspector and have had good results helping many people recover 'broken' USB sticks.
