The 1000 newtons isn't pushing down the diver because it is balanced out by the 1000 newtons of force from the downward direction onto the down surface of the diver.
This will happen if the buoyant force on the diver is equal to the weight of that diver
The principle of buoyancy holds that the buoyant or lifting force of an object submerged during a fluid is equal to the weight of the fluid it has displaced. The concept is additionally known as Archimedes's principle, after the Greek mathematician, physicist, and inventor Archimedes (c. 287-212 b.c.), who discovered it.
Applications of Archimedes's principle are often seen across a wide vertical spectrum: from objects deep beneath the oceans to those floating on its surface, and from the surface to the upper limits of the stratosphere and beyond.
Buoyancy is usually a double-edged proposition.
If the buoyant force on an object is greater than the weight of that object,
In other words, if the thing weighs less than the amount of water it has displaced—it will float.
But if the buoyant force is a smaller amount than the object's weight, the thing will sink.
It stays at same place if both forces cancel out each other.
