Why the map you grew up with disagrees
On a Mercator map, area grows with distance from the equator. Cambodia sits at about 13° N and is stretched to 1.05× its true area; United States at 45° N is stretched to 1.98×. That difference is why United States looks so much bigger than it is next to Cambodia. The figure above uses the Equal Earth projection, where every square kilometre is drawn the same size.
