it depends on intensity of blur, and also there can be different noise.
For example you can try to use camera with high ISO at night, and then blur image. You will see that blur doesn’t remove noise.
That’s because it’s not Gaussian noise which have normal distribution, noise from camera can creates blocks, lines, artifacts, which will be visible even with high intensity blur.
