How can I learn about the inudstry as a complete beginner? (Possibly stupid question)

Apologies in advance if this is a dumb question.

So, I'm currently a law student and my goal is to enter a field of law that doesn't pay well, and on top of that a job that pays even worse (it's a dumb passion thing. Don't ask.) Things being as they will be, I'm interested in ways of supplementing my income. While doing some very precursory looks, real estate caught my eye as an area of investment -- especially something like development. So, here comes the dumb question: How can someone with essentially no financial background learn about real estate? Learn about development? Keeping in mind my goal isn't to work at a place like Blackstone so I'm not pursuing an MBA. The research I've done seems to expect a baseline knowledge and background that I don't have. Any help would be great and extremely appreciated, even just pointing me in the right direction.
