Looking at https://www.grc.nasa.gov/www/k-12/airplane/wrong2.html it doesn't look like it's true that it's air being deflected that causes lift. There was a recent submission on HN explaining the theories of lift in sails: https://news.ycombinator.com/item?id=13829625. AFAIU air is not dense enough to make this deflection account for the magnitude of lift forces actually observed.

The NASA article discusses a deliberately simplistic model that does not consider the deflection of airflow over the top of the wing, but it would be easy to overlook the caveat if you don't already know the answer. Further down the page there is a link to a correct Newtonian flow-turning model.
