As I understand, radiation therapy is basically directing highly concentrated x-rays/gamma radiation to kill tumors/cancer cells. I don’t quite get how, in this process of “shooting” high energy beams at the tumor, the skin/muscle cells don’t get damaged?

It works the same way they can create images inside of a glass cube. Those glass cubes are cracked at specific points within the cube by directing multiple lasers at the same spot from different directions. No single bean is powerful enough to crack the glass but where they converge enough energy is directed to create a small crack. The radiation works the same way using X-rays instead of lasers. No single beam is very powerful but the point of convergence gets a much stronger dose of radiation.
