JPG has 8 bits per color, RAW formats have 12 or 14.

8-bit color/24-bit color depth is perfectly adequate for a final image.

However, when doing any sort of color adjustment (brightness, contrast, temperature etc), the image colors are nearly always remapped to a smaller set of colors, as computer colors are integers rather than floating point/real.  Observe a luminosity histogram while applying a tone curve to see this in action.  On smooth gradients like the sky, sunsets or untextured walls, this leads to a banding/posterization effect.

RAW images, with their greater bit-depth, offer considerably more latitude for image adjustments before a visible breakdown of image quality.
