First off, I have no interest in being a mathematician. Math was always and continues to be quite difficult for me.
So, as an outsider to advanced math, it blows my mind that there are people who’s entire job title is mathematician. How does that work? What does a mathematician do?
You out math people who have money so they give money to you.
The trick is you make it a complex black box so that no one knows how it works. See debt derivative models.
