I have one more question. Is white rice actually made of white, refined flour?

No, white rice consists of grains from the rice plant. The "milling" process removes its husk, bran, and 'germ', but a kernal of rice remains. It is not turned into flour.
White rice is nutritionally not much different from white flour. Both are starch, devoid of vitamins and minerals found in the bran and germ. I would classify it in the nutritional same category as white, refined flour.
