So with Elon buying twitter for 54.20, does this mean (me) buying at any price below this guarantees a profit?

I’m new to this and have never experienced a company going from public to private. I read around and I see that apparently shareholders are supposed to receive a tender offer for him to buy our shares from us. Does this mean that no matter what price I buy it at, as long as it’s below 54.20 I will make a guaranteed profit? Is 54.20 the last price that twitter will be before it goes private? Do I have to actively sell it in my brokerage account or will I receive an email of some sort? Any info is helpful!
