Why doesn't the house collapse under the action of atmospheric pressure?

I learned something in this junior high school ... the world is full of air ... there is atmospheric pressure outside the house and atmospheric pressure inside the house. The two are in balance, so the house will not collapse. Also, if the air velocity on the surface of an object becomes faster, the air pressure will also become smaller. That's why when you drive, open the window and the wind blows in. This principle is also applied to the flight of airplanes.
