You’re misunderstanding brother. These %s are from the amount of sunlight hitting the earth’s surface. You can put out a meter and it’ll tell you what wavelengths primarily make up the light. The sun only gives off a tiny bit of high energy rays. Check out pic. The black section within the chart shows a breakdown of the wavelengths of light hitting the surface of the Earth. The chart goes off screen like you said because there are tiny amounts of these super high energy gamma rays coming out randomly. But tons of what hits the earth’s surface is visible light.
You’re right about the spectrum going on forever. They keep just detecting higher and higher energy particles from crazy distant stars. But the sun is very stable and not too big so we don’t get a lot of those.
