Formatting a memory card, or PC hard disk WILL NOT delete the content, it will simply flag the content as being available for re-use.
The only way to ensure that any content is completely eradicated, on any media, is to first delete the content you want rid of, and then fill the medium (memory card, hard disk etc) with lots of other content until it is full up.
The easiest way to do that is to get hold of a large video clip. Copy it repeatedly to the media using different filenames each time until the entire card or disk is full.
Only then can you be sure that the original content is gone.

I have had a computer of one sort or another in my home since 1978, which is 39 years of tinkering with both hardware and software as well as building and repairing them and I do know what I am talking about.

What you say is correct about overwriting data is the way to go in order to eradicate sensitive data. This is a must-do if you intend to hand on an old hard drive - or SD Card - to someone else for them to use. It pays to be cautious these days.
As a further tip to people, an alternative to the method of copying large files over in order to overwrite sensitive data is using software that will do all the overwriting for you. If you are really security conscious you can set it to do multiple passes! Hunt around for free ones such as CCleaner to save a few bob.

All it does is remove the Address Tables. (If a drive was a book you'd just be tearing out the contents page.) I frequently recovered data from drives that were accidentally formatted when I helped out in a computer shop. It takes time but not much actual effort. A friend of mine recommended Spinrite a few years ago and it became an invaluable too for us. Just Google for Data Recovery Software and you'll find that as well as other software, very often for free.
Data can be recovered even after a few "overwrites".
I use a ministry standard program called DBAN (free!) to wipe hard drives & stuff. That will keep my bank accounts from leaking out!
