How is it possible for the IT experts to recover data that was erased from a hard drive when the storage of said hard drive appears empty?

And additionnaly, isn't there a way to exploit this so we can store more stuff on PCs?
Edit: can't thank you all individually but thanks to everyone, I learnt something today, appreciate all of your replies!

From my limited understanding deleting something on a hard drive is just letting your computer know that that space is now available for other data to be stored there. Until something is actually stored there the data isn't changed.
You can't use this to increase storage in a computer because the total amount of data allowed on a hard drive doesn't change when data is deleted. It just moves that stored data to the available section.
