Think Biff from Back to the Future. If time travel exists and I go back in time to bet on sports, will the outcomes occur exactly as they did?

For example, let's think of basketball. Even the best players only shoot around 50% from the floor. So let's say I'm betting the money line on the Lakers to beat the Mavs. The Lakers are down 99-98 with 1 second left. Kobe drains a fade away at the buzzer, Lakers win 100-99. Realistically, Kobe only makes that shot 50% of the time. So if I go back in time to that exact moment, does he hit the shot every time? Or, instead, will he make that shot 50% of the time when I go back and miss it the other 50%?

Even if you change the past (which, by BttF rules, you will, just by existing there as a time traveler), the change will ripple forward to the future and your knowledge of the outcome of any event will be updated to match the new timeline. So when Biff went back and won all those bets and created the Hell Valley timeline, his sports almanac was constantly changing to reflect the new outcomes.
