What makes you think psychics don't win the lottery? Just because they don't advertise that they won, doesn't mean the didn't. Besides that, many REAL psychics think that using their talent for personal gain will negate their abilities. However, we can't be sure many psyhics haven't won the lottery and failed to proclaim they are psychic. Would you?
Of course I would. Winning the lottery would be like a psychic's bona fides.
