can people be naturally unlucky?

We have no evidence that luck is a quantifiable property that some have and others don't.

Some people can certainly be naturally clumsy. Other can certainly be the sort of people who put themselves into situations where they get favourable outcomes. None of that however proves anything about 'luck'.

And to reverse it, can people be naturally lucky? Depends on how you view 'luck' and what it is. As a random event, with probability and percentages, there has to be an unlucky person to average out the lucky ones I guess.

Yes some are born to be unlucky all their lives while others keep having good luck like it says in the Bible life seems to be so unfair

Absolutely not. Luck is what people make it,unlucky,is caused by wrong decisions,such as walking a path not your own.

sometimes i think yes, the amount of luck some people get is just unreal and i can't remember the time i ever got that lucky

Luck is a point of view.

depends if you believe in fate
