Let's look at the difference between 35 and 36.

One more and the options change.

This is the first step towards understanding all one needs to know about the universe. With 35 balls one can't form a square. This matters. The underlying principle matters. Things are possible when you have a different number to work with.

With 36 you can have a full square.

And ...

A triangle

All of physics. All of chemistry rely on simple numbers. Small differences in those numbers makes a world of difference.

Structures depend on a specific numnber of building blocks.

There is much more to it than that. Lots to consider. However, understanding how basic building blocks have limitations leads to a profound understanding of the universe. Knowing that there is only one way the universe can be built, leads to the conclusion that it didn't need designing.

If it didn't need designing, what did the universe not need?

It did not need a designer.
