You can roughly categorise luck into 3 kinds:
1. Blind luck- Getting lucky via drawing a lottery.
2. Hustle luck- Getting lucky via working really hard.
3. Reputation luck- Getting lucky via credibility & building yourself.
To succeed in long run you should always focus on being credible. Reputation luck is the highest degree of luck resulting from years of building reputation & compounding out off it.
Most people depend on blind luck to be successful, which is roughest path to success.
