I have seen on online home renovation vidoes that people in US houses in India/Pakistan/Bangladesh/Middle East are made of bricks/concrete.

Only the wood studs are structural, the gypsum boards (also known as drywall) exist only to divide the interior of a building up. They are screwed into the wood studs and hang off them. The joints are taped, mudded (not actual mud), and then the surface is sanded and painted. Another way to do it is to plaster the entire wall, it depends on what kind of wall product is being used. The walls on the outside of a house is some kind of wood product like Orientef Strand Board (OSB), that’s covered in a vapor barrier, and then a siding material covers that. If you see any modern brick buildings in the US there’s a very good chance that the brick is only a veneer and not structural.
The advantage of drywall is cost and installation. Drywall is a cheaper material, and it’s quick to install. The void between studs are used for insulation on exterior walls, so no need to find or build in space for insulation as the construction method naturally leaves voids.
