How much do publishing agencies pay you for your book?

I know a girl who is published with an agency and I'm assuming they pay a lot cause she quit her high paying job to work with them. I might be able to convince my cousin to help me with the sales pitch. There is just one thing, which is I'm not sure I picked the right pen name for my book.

I've know people in the publishing field

It's based on commercial viability so a Harry Potter type of deal would have been millions apiece like 10's of millions by the last few

Some niche publications I've found are basically available on eBay and Amazon and are paid per sale so become a passive income for the author

They usually aim to get the costs of printing, marketing, editing and pre-socialisation payed by the author (s)
