Well big money don't make it sure that you will have profit, if it did then the users who lost those btc won't be in negative. Luck is same for everyone its just the right time when you withdraw those btc you won.
For sure people with higher balance has a good chance to win this competition. But don't forget! They can lose their bets too. Higher risk higher chance to win this competition. It's pretty fair to me!
ofcourse there is nothing sure in gambling, but those people with high balance have the advantage to win this contest. how? because for example i have 10btc balance, i can wager 1btc in a bet and if it win i will have 1btc profit and easily in the top right? if i lose, i can easily create new account, wager 1btc and if win i will have the first spot in the contest, easier to get .4btc top prize right?
I agree with you on this. Why would you want to give additional rewards to the winners, when it's the losers that actually need support. The winner will be happy and will come back to play again, a loser is out of the game, unless he gets a reward that will allow him to keep playing, or sweeten up his loss a bit.
A wager competition, like the last one, is a good choice too, because it gives more equal chances to everyone. You can wager the same amount in 100 bets when you're poor or in 1 high roller bet, but you can do it.
