<I put up 500,000 black dots and 500,000 red dots on my board. I have a cannon that fires 500,000 bullets at once. Each bullet must hit either a red or a black dot--but it must hit a dot. Surely I'll have 250,000 of _each_ left over.> You might have 250,000 of each left over or you might have 500,000 red dots or 500,000 black dots left over, or some result in between, assuming that what color the cannon hits is purely random. If I flip a coin 10 times there's a chance I'll get 10 heads in a row. In fact, if I flip a coin long enough, I guarantee you I'll get 10 heads in a row at some point. A college professor gave his probability students the assignment of flipping a coin a certain number of times and recording the results, or just pretending they flipped the coin and inventing the results. Each student's choice. When they turned in their papers, he looked at them and guessed who'd actually flipped the coin and who'd faked it near perfectly. The fake ones didn't have enough flukes. Random produces flukes, unfortunately.
