Can anyone help explain Obamacare like I'm an idiot?

Here's my attempt to explain my understanding like I'm an idiot:
-If you're below the poverty line you qualify for Medicaid (not new), but Obamacare expanded Medicaid
-If you're not poor but not too rich (1x-4x the poverty line), Obamacare gives you tax credits to offset the cost of purchasing health insurance
-If you're too rich (> 4x poverty line) there's no change. You're free to go purchase your own health insurance like before
-If you've got coverage through work Obamacare changes nothing
-Regardless of which of the above you fall in, Obamacare made it illegal for insurers to decline people with pre-existing conditions
-They paid for this all somehow but I don't know how but its safe to say Republicans probably didn't like it

Am I close???
