Luck is random. No one is consistently luckier than someone else unless you believe in the paranormal.

If someone poor advanced in life and got really rich, is he luckier than others? I don't think luck has anything to do with it. If you got significantly richer - It means you had to consistently be smart, work hard and make the right choices over and over again.

A lot of rich people become poor. Is it because they are unlucky? Or is it because they made poor choices?

If someone got lucky, it's just one time. Most probably, they will have misfortune the next time and things will even out.

Consistency is anything but luck. Life is a marathon, not a sprint. To get ahead you need persistence, not luck.
