That's true. With the Box-Muller method, there is the log(~U1) term, but you can always just add a small value to U1, which will truncate your distribution. The size of the small value can be calculated to fit with any given threshold.
With white noise there should be no preferred values but gaussian noise will have a lot more hovering around zero.
