Only if the noise in question comes from the trigger electronics.
In the case of a 60Hz mains derived signal, most of the noise is
going to be riding on the signal, and will be amplified with your
gain stage. A -delta amplitude noise signal will be zero when the
sine wave signal is at +delta. That will be sometime other than
the actual zero crossing... which is phase noise.

You are missing that you can alter how much trigger jitter you get.
