Guys I'm so nervous, trying to calculate the odds to calm myself haha. A 1 in 5 doesn't seem crazy, considering that many underqualified applicants just 'shoot their shot' to HBS but I know how many great candidates are rejected without interview every year

Just some advice, thinking in terms of the odds or acceptance rates creates a false sense of security. HBS and any other school for that matter have no incentive to admit more people than are good enough for them. If there were only 700 people that met all of HBS's criteria, they wouldn't still take in an additional 300 just to meet their previous acceptance rate. So as much as we all like to think of this as a numbers game, it really comes down to whether or not you are good enough for the program.
What might be comforting to know is that there really isn't anything left in your control now. If you gave it your all, poured your heart and soul into your app, and wrote the greatest essay of your life, then even if you are rejected, you should be comforted in knowing that there really wasn't anything else you could have done. And even if you didn't give it your all, you still can't do anything about it. So that should be a little freeing. What's to be will be. I believe it was the Dalai Lama who said something like: "If a problem is fixable, if a situation is such that you can do something about it, then there is no need to worry. Because you can fix it. If it's not fixable, then there is no help in worrying, because you can't fix it. There is no benefit in worrying whatsoever."
