21% :)
..... There aren't opponents in blackjack. just the dealer and the players. If 2 players both have 21, and the dealer doesn't they both win regardless of what cards they have.
Most players will take the even money, it is always a sure win. If you don't and the dealer has blackjack it is only a push.
Probably, You're not gonna be able to find the answer to your question in a place like this, if you can understand why... I would recommend you to subscribe to a Blackjack forum (and/or clubs) dedicated to professional players. There you'll find real users of the Babum Blackjack software; and if you're lucky enough, perhaps you'll get to hear one of those amazing stories about the latest techniques (to win big at Blackjack) that have been developed with astonishing results.

You cant win
Blackjack is not a multiplayer game. It is a casino game where there is the dealer and the only player is you. In order to win the stake, you should either get 21 points in your first two cards (Blackjack), surpass the score of the dealer after the hand is stuck or the dealer's hand should be bust (higher than 21).

In blackjack, the dealer only shows one of their cards to the players while the other card remains hidden until the end of the round.

I believe the name "blackjack" may have come from the fact that originally players were paid extra when they were dealt a spade-suited blackjack with an Ace and Jack.
In blackjack, the dealer has to hit on a hand total of 16 or less and stand on a hand total of 17 or more in order to win.
They do not always win. There is a chance for the players to win as well, but the casinos everywhere gets some profit from any type of gambling, for example, Blackjack, Texas Hold 'em, Slot machines and such. It does indeed look like the casinos always win, but in reality, they don't.
