If you have luck, there will be a 100% assurance the winning, as in all gambling games needs to have luck to win.
I always like to point to games where the underdog wins and all the commentators are stunned that there was "no chance of them winning"...
The fact is that if you turn up to play your match/fixture you have more of a chance of winning than if you did not turn up at all. There's no such thing as 100% chance a team will win. Not every time at least.
