Does the E-Value always define the filament length extrusion in millimeters and/or does it directly give a stepper rotation?

I understood on a fundamental level that E-value (in G-Code) was the length of filament pushed in millimetres. i.e. E=10 is 10 mm filament to push (with a firmware like Marlin translating this value ...
