Yes this statement is definitely true.
When the stem grows in girth there is a Meristematic tissue called Cork cambium , which develops in cortex region of stem.When this phellogen grows it cuts off the cells on both side.
The outer cell develops into cork or phellem.
The inner cell develops into secondary cortex or phelloderm.

Answer:
When secondary growth occurs in the dicot stem and root, the epidermal layer gets broken.
There is a need to replace the outer epidermal cells for providing protection to the stem and root from infections.
Therefore, the cork cambium develops from the cortical region.
It is also known as phellogen and is composed of thin-walled rectangular cells.
It cuts off cells toward both sides.
The cells on the outer side get differentiated into the cork or phellem, while the cells on the inside give rise to the secondary cortex or phelloderm.
The cork is impervious to water, but allows gaseous exchange through the lenticels.
Phellogen, phellem, and phelloderm together constitute the periderm.
