Face id is putting a very good camera very close to your face and asking it if the face inches from the screen and stationary with respect to the camera matches exactly one face.
Facial recognition is asking a worse camera if a moving partially obscured face is one of 338M legal residents and citizens or potentially millions of illegal folks. Since this is inherently an incredibly harder task it doesn't take much to make it impossible.
