AS REPORTEDno primary record reached; this is what the reporting says
Is it true that diffusion is the process by which a substance moves from a region of high concentration to a region of low concentration?
Yes. Multiple authoritative scientific references consistently define diffusion as the net movement of a substance from a region of high concentration to a region of low concentration.
