One effect of doing a low level turn is that your lower wing can be in air moving at a different speed to the air in which your upper wing is moving - due to wind shear. That can cause one wing to stall, followed by a spin and an impact with the ground.
The first sentence is correct, as Paul demonstrates. But airspeed doesn't cause a wing to stall. The AoA is the same for both wings, unless you're in a climbing or descending turn, in which case there might be a tiny second order effect.
