Only those whale gambler that gambling naturally with or without tournaments can win a wager contest on normal games including due to their huge bankroll and natural high wager.
It's always good to have a large bankroll to be able to make bets The few tournaments I've participated in have been poker but with a tight balance, It's true as you say because in those tournaments the one with the largest bankroll always wins because they are the poker players who leave you out because they make large bets and at that level, I can't compete Experience is key there because you know how to act at any moment. I don't have that well-established experience.
I have less experience on poker tournaments but at least on that game you have an edge if you are good on poker. I remember watching a lot of poker tournaments that low chips manage to beat the highest chip by continuously winning an all-in round with good hands.
On casino wagering contest like this one, it’s almost impossible to beat a high bankroll player if he is committed to win the tournament.
This is the sad reality for small bankroll player.
If you play in a tournament, it has nothing to do with capital, because all chips are divided equally among all participants, so far, that's what I know and I quite often participate in tournaments, skills and experience are really needed as well as patience too
