On Polymarket, the price of each side in a market represents the market's implied probability. A price of 100¢ for OG1 on the series moneyline means traders collectively believe there is roughly a 100% chance that OG will win this match. If you buy OG1 shares at 100¢ and they win, you receive $1 per share — a profit of 0¢ per share. If they lose, those shares are worth $0. The same logic applies to individual map winners, map handicaps, and total maps: a lower price means a higher potential payout but a lower implied probability of being correct.
