The greater the ionization energy of metals the greater desire it has to gain an electron?

I'm confused because my text book says non metals and metals react oppositely

Ionization energy of an element (say X) is the energy required for 1 mole of gaseous atoms of the element to remove 1 mole of electrons to form 1 mole of gaseous singly-charged cations, i.e.
X(g) → X⁺(g) + e⁻ …… ΔH = ionization energy of X > 0

Obviously, no matter whether it is a metal or a non-metal, the greater the ionization of the element, the more difficult for it to lose an electron.

The statement "non-metals and metals react oppositely" means that non-metals tend to gain electrons in reaction but metals tend to lose electrons.
