It utilizes the laws of principles of conservation of mass and conservation momentum. The latter is a consequence of the well known law, F=ma. Relating the Bernoulli equation to lift is a very tricky problem, but it was solved in about 1905 by the use of vortices as models to develop estimations for circulation around an airfoil. From that we get lift via the Kutta Jakowski theorem (lift= density x freestream velocity x circulation). You may know about JavaFoil to calculate pressure distributions on low-speed airfoils, which uses vortex math and geometry to find the velocities and pressures. Vortex models can be extended to the third dimension to analyze wings. CFD is used when a more accurate estimation of lift is required, and it uses truncated Navier Stokes equations to accounts for things like gravity, body forces, compressibility, boundary layers and viscosity.

I am not trying to show how many books I own just that it is silly to claim lift is due to X% Newton and X% Bernoulli. I admit I fall into the same trap because it is tempting to oversimplify to reduce the brain cells involved to gain a true understanding. Most of what we read is so oversimplified as to be comical.
