Question about status of _random changed

At 4:50, when you say the status of _random changed when we want to get a random number, I am a bit confused, since it is a static field in a static class, why _random is not immutable?

While it's common for static global objects to be immutable, just defining it as "static" does not make it immutable. And in this case it's necessary for it to change so each call will produce a different value.

What "static" does is to allocate space for it associated with the class itself, so an instance doesn't need to be created.
