When the throttle is fully released, is the throttle fully closed? Why?

Hello, car owner, even if the engine is turned off, the throttle is not fully closed. There is a gap. Because air intake is required during idling, this gap is stable for idling air intake. I hope my answer is helpful to you. You can keep asking me questions. I wish you a happy life?
