Others have shared great answers but a diagram might also help!

This is a diagram of a generalization of factorials called the [Gamma function](https://en.wikipedia.org/wiki/Gamma_function). Anyhow, the closer you get to “0” the closer the Gamma gets to 1. And at every other integer, Gamma is the same as Factorial. It’s a smooth function that connects the Factorials.

Maybe it will confuse more than clarify but I think it’s kind of cool.
