Everything in Recuva is geared toward recovery.
Well, yes, it is primarily a recovery utility.

It lists half a million files that are partially recoverable, totally lost, or fully recoverable.
That's a huge amount (I usually manage about 12k). Did you run a deep scan to get this number, or the standard scan?

Can I delete them?
Yes and no. Well, really no, but as near as makes no difference. A file can never be deleted. A virgin disc will have (presumably) a uniform magnetic pattern on its read/write surfaces. Once data is written then that's it, the surface can never be restored to its previous unsullied condition. What CC, Recuva, and anything else can do is overwrite the data. This overwritten stuff can always be recovered, but will be of no use or importance to anyone. If you use Recuva to overwrite the data you will end up (if Recuva ever ends) with the same list of half a million files, but with nothing of value in them.
There are diskwashers around that will erase the unused portions of a disk, by which I mean the areas not currently occupied by live files. In general they do exactly what Recuva does, but overwrite the entire not-live disk area with blocks of zeroes, or random data. They may also remove filename entries from the MFT, which Recuva doesn't do, so they will give an impression of having cleaned the disk but that is false, in fact the reverse, as they have contaminated the entire surface of the disk with their duff data.
It's inevitable that data gets written to disks, so it's not really worth getting too worried about it. If we didn't have Recuva (or similar utilities, if there are any) then we wouldn't be able to see these lost souls. If you want to
look clean, then a diskwasher may help. Rgds.
