No. Metamorphic rocks can also from front sedimentary rocks and from other metamorphic rocks.
Metamorphic Rocks
Metamorphic rocks are formed through the alteration process of existing rocks due to high temperature and pressure. They display a foliated or non-foliated texture, with minerals aligning in layers or bands in the foliated type. Metamorphic rocks may show a variety of colors, depending on the minerals present and the intensity of the metamorphic process.
The Acasta Gneiss, a metamorphic rock, is 3.96 billion of years old.

Metamorphic rocks can form from both igneous and sedimentary rocks through the process of heat and pressure, but they are more commonly associated with forming from existing metamorphic or sedimentary rocks. Igneous rocks can indirectly contribute to the formation of metamorphic rocks by heating up and altering surrounding rocks, leading to the formation of new metamorphic rocks.
Rocks formed from high temperature and pressure include metamorphic rocks such as marble, schist, and gneiss. These rocks are created deep within the Earth's crust through the transformation of existing rock types under intense heat and pressure conditions.

Unakite rocks are metamorphic rocks formed from the alteration of igneous rocks. They are typically composed of pink feldspar, green epidote, and clear quartz.
