A simple explanation, but also rather inaccurate…
If this works for you, that’s fine, but maybe don’t ‘teach’ this to others.
You might think it’s crystal clear to you now, but it’s obviously not. That is totally fine, at some point you will understand it.
Let me try and give a brief explanation here:
Each Object has an orthogonal Coordinate System. The center of that Coordinate system (where all 3 Axes meet) is called the Object’s Origin, just like the 3D World has its Origin at (0, 0, 0).
The Mesh Data is a list of the Vertices and their Positions (and other Attributes, but that’s not important now) (and how they are connected by Edges and Faces).
If you Move an Object (in Object Mode), you Move the Coordinate System, the Vertices don’t change their Position in the Object’s Coordinate System.
Same for Rotating and Scaling.
When you are in Edit Mode, you change the Positions of the Vertices, so the list gets updated.
A Linked Duplicate, uses the same list as the Original Object, but in its own Coordinate System.
A ‘normal’ Duplicate uses a copy of that list, so it can be Edited without changing the original Object’s list.
