Yes. You are right. White matter of brain is mainly composed of myelin sheaths, which surround the axons and gray matter is composed of nerve cell bodies.
Myelin Sheath Myelin Sheath
it contains myelin sheath which is a fatty white substance

An insulating layer that surrounds the axon is a myelin sheath.
The Myelin Sheath around the axon
The endoneurium surrounds and protects the myelin sheath.
Myelin sheath
A myelin sheath is a layer of myelin (a dielectric, or electric insulator) around the axon of a neuron.
Oligodendrocytes are specialized neurolgical cells that produce myelin sheath.

Myelin sheath, which is only found on long axons (white matter), not on short cortical neurons (grey matter).
