How could everything in the very early universe occupy such a small volume? Is it because particles are described as point-like meaning on there own they take up no space or volume? Please help.

They say for every billion antimatter there was 1 extra matter, & there is SO much matter still in our universe. So is it accurate to say in the early universe there was billions x the total mass of the universe now? All the matter & antimatter is now just radiation & neutrinos zipping around space? There must be an absurd amount of radiation then? Please correct me if wrong. thanks
