In my opinion yes ultimately all rocks are derived from igneous rocks, but we have to keep in mind that rocks are always in movement. With reference to the rock cycle this could be explained better. The Rock Cycle was probably the first of Earth's cycles or systems to be recognized and studied, at least in a qualitative sense and it is made up of three rocks, igneous, sedimentary and metaphoric.
Igneous rock can change …

…larger crystals. Because this rock changes, it is called metamorphic. Metamorphosis can occur in rock when they are heated to 300 to 700 degrees Celsius.
When Earth's tectonic plates move around, they produce heat. When they collide, they build mountains and metamorphose the rock. The rock cycle continues. Mountains made of metamorphic rocks can be broken up and washed away by streams. New sediments from these mountains can make new sedimentary rock.
The rock cycle never stops.
