Knowledge to manage.
Luck to win.
All three has their own importance and individual role in gambling. But which is most important one for gambling. Can we manage to be profitable with any one of them. What is your opinion.
Depending what you mean by money to start I think it doesn't matter. I mean if you have a ridiculous amount of luck then you could work it up to a large amount of money from licking the faucets. Money management would be a big deal but again if you have a lot of luck until that runs out money management wouldn't be that important either.
I don't believe that many if any would be profitable with just one of them other than luck. Even if you have all three the chances of staying profitable are small at best. Luck doesn't hold and that is obviously the biggest factor.
Luck while lasting would workout.
