what makes omegaverse confusing is because some mangaka change the original concept a bit.
i was confused at first,
but as i read more and more omegaverse stories, i can already understand the concept even tho they change it a bit.
different manga, different 'type' of omegaverse (usually. but the different is not too big).
so maybe you can read more omegaverse stories.

This is slightly better. Most authors will take the time to describe omegaverse. https://www.tumblr.com/tagged/omegaverse+explained
How do I learn about alphas, omegas and betas.. Who gets pregnant and stuff like that? I have no clue. I thought I knew but there's a manga that I'm reading that is making me lost, I never actually learnt or read about that universe..Help
