How does beta decay release an electron(or a positron) from a nucleus which consists only of a proton and neutrons?

The wikipedia article is kind of...totally Greek to me so I'm a little confused about this. Thank you for answering!

Beta decay does not release an electron or positron. Rather, in beta decay, an electron or positron is created.

Let's look at a free neutron. When it decays into a proton, an electron, and an anti-neutrino, what happens is the neutron ceases to exist, and the energy of the neutron forms a proton, electron, and anti-neutrino instead.
