After deleting files from the Recycle Bin in Windows, where do these files go?

Here you just need to understand what a file is and how the file system works.
A file is a piece of data with a name.
When you write it, several things happen -
1) The data is written to the disk, in specific "cells" on the disk that have numbers.
2) The file system writes to the database information that such and such a file is stored in such and such disk cells.
Consider moving to the trash.
If you delete a file in the trash you just move it to another folder. There is no removal. Just moving.
But when you delete a file completely, without any recycle bins, the following happens -
the file system removes from the database information about where the file is stored on the disk.
And this disk space is declared free. You can write new data to it.
And the data itself, as it was on the disk, remained there, and it will not be known how long it will be there until someone writes new data to these addresses.

to heaven - immediately to paradise.
they are physically removed from the file system - ie. in the file system index, the mark of their existence is erased.
But the content of the file itself remains on the device.
What undeleters use is to scan the entire amount of free space and look for file headers. If you're lucky and nothing was written to the blocks where the erased file lies, then it can be restored.
