Usually, yes. This is to make it appear always the same
dimensions. If you used pixels, the image would look very small
when printed, and very large on a low resolution display. So, you
just tell it how big it is, and the software scales it to the
right size on any device.
Of course, how well it does the scaling depends on the software.
In PDF you can decide if you want interpolation or not.

You usually should think in terms of what your document is, not
what it looks on a particular device. I.e. a 10x8 inch photo
should be 10x8 whether you are looking at it on paper, or on
