This is incorrect, while most runways are aligned with the magnetic heading, that changes when you have a field with multiple parallel runways. Atlanta Hartsfield comes to mind first, with its five parallels in the East-West directions, 8L/26R, 8R/26L, 9L/27R, 9R/27L, 10/28. One would naively expect these to be not parallel by just reading the name, while in fact they are all in line.

And they're only magnetic until they get updated because the declination changes over time.

Other exceptions: near the poles where the magnetic declinations change rapidly, so they use something else.
