What's usually your pick as a gambler since sometimes some persons are luckier than others?
I don't believe in personal luck, and I go with chances in casino games because it's hard to be lucky with 5% winning chance, you know what I am sayin? While in sports betting, I go according to my knowledge irrespective of odds.
Makes no sense to say you go with chances -- the tendency that one can claim a win in gambling (be it sport betting/ casino gambling), but you don't believe in luck. How do you define luck?
You go with 5% winning chance roll in dice, and win that roll then it's luck, because there was minimal chance to win that roll, you have to be lucky to win this bets.
As for me saying, I don't believe in 'luck' — you can re-read the statement you quoted, I meant 'personal luck' there implying I don't believe in one person being luckier than others — this was remark to op saying, "some persons are luckier than others".
