FWIW, the odds don't work like that. It doesn't matter how many times you have flown in an aircraft. Every time you takeoff, the odds reset so that, say there's a 1 in 1 million chance of an accident, then that's the odds for EVERY flight. It's just like playing roulette. Every spin is a new game, so it doesn't matter how many times that, say, red has come up. Each spins means you have a 50/50 chance of getting red. So it's the same with flying. Much better odds of winning, however.
As a former Navy Aircrew with 5K hours of combat aircrewtime, I can tell you that accidents are extremely rare, though "mishaps" are slightly more common. But it's still safer than driving your car.
