Let me tell you how a hard drive works.

It puts files on the drive, they exist until the file system says that space on the drive is now available for new data to be written to. So this is how a normal delete occurs, it just allows that space to be overwritten.

So technically the deleted files can be recovered using special software that directly reads the 1’s and 0’s of the bits on the drive itself, not what the file system is telling it.

However the longer you use the machine, the more chances that deleted data can be overwritten, and most certainly will occur if you surf the web and download software, however likely only partially since you deleted a lot.

So the object is to boot the computer from another drive or disk, then install data recovery software ($100) and recover your files not to the same drive (less it overwrite the unrecovered files) but to another external drive.
