So victory is not due to luck.
Maybe this tournament is aimed at those who are able to spend a lot of money, but spending money on bets will pay off in a very valuable way because the winning prizes are many times bigger than the money used to participate in the tournament.
Luck does matter here just like in any other gambling game to a certain extent. Spending lots of money doesn't guarantee that you will win if luck doesn't side with you. Invest only what you are willing to lose.
The first prediction was placed. I don't think it's logical to become a winner again 😉
It's completely logical since both events are completely independent of each other. One example is LFC who win two events back to back.
