32-bit means 32 bits-per-pixel (bpp). I would disagree that many people
think of it as 4 billion colors: 32 bpp includes three separate color
components, red, green, and blue, and possibly transparency (alpha) also.
So total colors is approximately '4 billion / 4' or '4 billion / 3',
depending on how the colormap is set up.
