There's an infinite amount of whole numbers, naturally, since you can always keep adding one. But there's also an infinite amount of even and odd numbers, since you can always keep adding two, too, even though they are just 'half' of the set of all whole numbers. Along the same line of logic, there's also an infinite number of multiples of 40 quintillion, since you can always keep adding 40 quintillion. Suddenly the odds for any headcanon (whole number) to be in a parallel universe (multiple of 40 quintillion) are astronomically low, right?
But it gets even worse, since there's also an infinite number of these non-contiguous infinite sets - just consider the 'numbers to add by' for all infinite sets in the whole numbers as its own set, and it becomes obvious that here, too, you can just keep adding 1 infinitely. And since the gaps between the numbers get larger and larger the chance that any headcanon exists in any parallel universe keeps shrinking.
In other words, the chance tends to zero.
