Now it’s true the Eagles won the super bowl. Is the following statement true.?The team had always a winning chance of 100 percent regardless of their preparation , and there was absolutely no power in the world that could have changed the outcome .

Let's focus on one bit of your question. You ask if this is true:

          The team had always a winning chance of 100 percent regardless of their preparation.

Now compare that to something more mundane. As I write this, it's 3: 45 here in College Park. The light in my office is on. Would you say this?

          The light always had a 100% chance of being on at 3:45 on February 15, regardless of whether anyone flipped the switch.

I'm guessing you'd say no. The flipping of the switch was an essential part of the process that turned the light on. Likewise, the Eagles' preparation was an essential part of the process that brought about their win. No switch flipped, no light on; no diligent preparation, no win.

It's not that this answers all the questions someone might have about freedom and determinism (or, in this case, freedom and determinateness). It's just to say that there's no reason to think things would have turned out as they did regardless of the events that led up to them. The possibility you're asking about is sometimes labeled fatalism, and the belief in fatalism is often a consequence of overlooking the point made by our little example of the light switch.
