Theres community buses at my campus have a VERY large print along the side that say. “Powered by clean natural gas”. What does that mean. Isnt all gas natural?

It means that burning it doesn’t release toxic fumes. But that has little/nothing to do with the greenhouse gases that cause climate change.
Burning any hydrocarbon (methane, butane, propane, gasoline, etc) causes it to react with oxygen to produce heat, water vapor, and CO2. By calling it “clean” they really just mean that it’s pure, and that there are few/no other byproducts that could be hazardous.
By calling it clean, they mostly want to mislead you into thinking it’s fine for the environment. But there’s no way around the fact that burning any hydrocarbon for fuel will release CO2 into the atmosphere.
