Why do we not see a lunar eclipse during each full moon when the earth is in between the Sun and the Moon? Does it depend on the seasons?

I looked this up online, and it seems like there is always a lunar eclipse when the earth is between the Sun and Moon in alignment...

the orbits of the Moon around the Earth and the Earth around the Sun are not co-planar

sometimes the bodies align for an eclipse , and sometimes they don't
