A better way to put this question is : “Why can’t any situation have the probability of it happening, equal to one or zero?”
Simply answered: a system cant’t exist independent of its surroundings, or isolation is hypothetical if existent.
Even if the probability of a happening within a system is zero, the surroundings do affect and in some situation are the only cause of the effect.
Why can’t a system be isolated?
This is because the system was created by the surroundings AND in place of them. A portion of space was occupied by system 1 that obviously had an effect on that particular part of space. This effect led to the creation of the new system 2 (for which now, system 1 is the surrounding). Since system 2 is an effect of system 1, system 1 is someone present in that part of space ( even if it is just an effect). Therefore, system and surroundings can’t be independent.
To explain this very simply, take a hypothetical king. The king’s son kills the king and takes the thrown. Though the kingdom is not ruled by the king now, the king’s son carries the king’s genes and therefore, the king still affects the kingdom.
The most common example of having zero probability is rolling a dice and getting the number 7. I hope you are creative enough to think of a situation when number 7 might appear.
Then why do we seem to see certain things as “impossible”?
If I ask you to choose a number between 0 and 1, it is possible that I guess it. But because the probability is too low, we assume it to be impossible.
Take another situation; a box filled with many many red balls and 1 blue ball. If a people are asked what the probability of taking out the blue ball at the first attempt is, majority of the people will perceive it to be more than what they would have in the case given before (numbers between 0 and 1). So, it all comes down to how we perceive situations and to where we set the “impossible” limit.
Fun fact: You are 1860 times more likely to be hit by a world ending asteroid than dying in a terrorist bomb attack.
Freaky fact: You are more likely to die on your birthday than on any other day in the year. Happy Birthday to you.
