python - Confused with the "not" operator in while loops and if statements

So I'm a total beginner when it comes to Python and the "not" operator is kinda confusing me. So i was watching a BroCode video and he wrote this code:

My question is: Doesn't this mean; while name is not nothing, do this? Isn't "not" supposed to make things opposite? So by that logic this code is not supposed to work. The condition of the while loop is that the name needs to be something, but it's not, so why does it even execute?
