This is kinda a weird thing to call "luck" though. "You" could also have been born a duck, a 1000 years ago, in the future or in another universe (maybe). But then "you" would have been somebody else and hence, not "you" at all.
In other words, "you" had 100% chance of being you. No luck involved.
I definitely agree. The universe being almost certainly deterministic, there is also a 100% chance of everything that has ever happened happening.
It's still useful to think as if different people could have been born in different circumstances. You could think of it as a mental shorthand for the idea that differences between human beings are arbitrary, and it makes no sense to argue that a human inherently deserves an impoverished life over another human.
I still think you're making a categorical error. "being human" isn't a privileged class that inherently deserves something. That way of thinking becomes really messy fast in terms of drawing concrete rules.
It also seems a bit homo-centric coming from a human.
BTW, I think we do have genuine subjective probability, even though the universe is deterministic.
And what event or circumstance are you talking about? Nothing happened to you when you were born - because you are an emergent entity that is defined by your life.
This isn't like flipping a coin: it could come up heads or tails.
You must be thinking of some kind of immortal soul.
