Do you mean if a 100 people picked the winning number, they'd each RECeiVE only a 1/100th of the total prize?
Yes. Horse race tracks pay out on winning bets the same way. A pro learns to follow the money. You may *know* the horse will win, but if everybody else bets the same horse the payout still won't match the risk. And there's ALWAYS a risk. Even in a fixed race.
