Solve this DUPLICATES issue one and for all

I need to know the following:

I have a Smart Folder for Duplicates. (I am patently aware that some dupes may be bookmarks or tags.) But I have no patience for this task before me. I am at the tearing my hair out stage and want to eliminate the one variable I don’t understand.

So my Duplicates question is this:

If I select everything in the Duplicates Smart Folder and delete via Option-Command-Delete, am I also eliminating the original, wherever it may exist in my databases?
