You should first think what your goals are. The 30% chance is a bit optimistic, take a look at the first lesson on How to start a startup https://startupclass.samaltman.com https://startupclass.samaltman.com If your goal is to make money then joining FAANG is the safer path. To reach unicorn level in a startup is always risky long shot, unless you already know you are joining a rocket that is on a market dominance path and you are getting a great equity deal. There are plenty of ex-FAANG starting startups so you could have a good chance of joining a couple of years down the road. Good luck!
