I'm sorry, I'm going to try to be nice, but no, you don't either know how to play or not. Sure you do either know how to play or not, but it's not finite. No one knows how to play before they learn. Like with anything, you have to learn how to do it.
And like with anything, the best way to learn is to go to experts who have a demonstrated knowledge of how to do something. That's not saying that everyone who demonstrates an ability to do something is the best to teach others how to do it, but if you can't show a high level of doing something, you probably shouldn't be speaking to it.
