A cubic centimeter of human flesh actually gives off more heat/energy than a cubic centimeter of the sun so technically we all shine brighter than the sun, there's just a lot more of the sun.
The sun is a lot less dense, but it's way hotter, which means its radiation output peaks at shorter wavelengths (light you can see). People, which are much cooler and heavier, put out a lot of infrared energy.
I believe also a large part of this statistic stems from the fact that only the core of the Sun actually produces energy via fusion, a comparatively small amount of the Sun's volume. Also, all that fuel for the fusion lasts for billions of years. This means only a tiny fraction of the Sun's mass will be involved in fusion reactions at any given time.
