Think of it like a wedge. 10 pounds force on the back of a wedge can easily cause 100 pounds force perpendicular to it.

But there is a tradeoff between force and displacement. Larger force = smaller displacement.

Same with a wing. The thrust force is lower than the lift force, but the horizontal displacement (velocity) of the wing is much greater than the vertical displacement (velocity) of the deflected air.

i.e. small force x large velocity = large force x small velocity
