Good question. The non-woody roots absorb and the woody roots are for
support, manufacturing vitamins, storing sugar converted to starch and more.

Beware of so-called tree experts who do not understand tree biology.
Storms, fires, floods, earthquakes, and volcanic eruptions keep reminding us
that we are not the boss.

Isn't it true though that deeper roots add strength to the tree, that is,
hold it firmer in winds?

There is no requirement of trees that you deep water. The non-woody
absorbing roots that absorb water with essential elements dissolved in it
are most of the time in the upper four inches of soil. The biggest
problem during drought is over watering.
here is an article on where absorbing takes place.
