I am going to take you at your word that you aren't baiting me. Yes, you can (and people have) predicted where a roulette ball will land while it is in motion, particularly if you have the aid of cameras. This is more useful in European Roulette and American Roulette - but it can work. What you can't do, is come up with a positive expected value through any kind of betting pattern.
