They don't only drive it to a lower depth. when the dive plates is angled so that the u-boat is going to surface, it will keep "fighting" against pressure IF you have set the u-boat to a specific speed.
There comes a depth when the u-boat cannot handle anymore depth and needs speed to compensate for it. This is where you're mistaken.
It's not a submarine btw, it's a u-boat.

Just as an Aircrafts Ailerons, Rudder and Elevators help it achieve its altitude.
The difference between a Submarine and an Aircraft though is that the Aircraft needs to be constantly moving at a certain speed and angle of attack to keep flight.

It doesnt need to constantly keep moving to keep flight. This is where you are mistaken. A piper cub can fly with zero velocity. It's called velocity, not speed btw. You seem to misunderstand the principle of flight.
When you angle the u-boat upwards, you decrease the surface of the u-boat and therefore lowers the water pressure from above by huge numbers.
