My question now is, As a gambler would you give 100% to a stake that you trust?
You can trust your favorite team of fighters as long as your analysis tells you that your favorite team of fighters has a chance to win a battle, it's ok to have 100% trust as long as you do analysis, but if there is money involved and in your analysis and your favorite team has little chance to win then you have to do the right thing and don't bet on them to protect your money or better skip betting.
It's ok to be a fanatic in one team or give them 100% of your trust but you don't throw your money your favorite team is the underdog, your money should be more important to you than your loyalty.
