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.
