ELI5: Why is the ratio of protons and electrons in the universe 1:1? Is there a mechanism keeping that ratio steady or did we just get really lucky when the universe formed?

Is this one of those "it's that way because if it wasn't we wouldn't be here to ask it" questions?

When the universe started out from “nothing” in the Big Bang, its total charge was zero, and when the particles were being created, that total charge was staying zero at all times, and is thought to be exactly zero to this day. So in every possible particle creation process for every one positively charged particle created one negatively charged particle appears as well.
