Not only in gambling, luck is needed in every place, in every field of work, and skill and experience are complementary to each other in every field. You can never win gambling by relying only on luck, you definitely need experience and skill. However, the amount of winning in the budget can be increased based on experience and skill, when I bet, research strategy depends on experience and skill and luck, and I bet on both football and cricket teams and I always research on both teams.
This increases my experience so that I can use my skill and experience to bet again in the future, so the chances of winning the bet are higher.
Yes, success depends on the combination of luck and skill, experience, here you cannot achieve success without any of them, so you can never do anything that is too risky by relying on just one thing. In the same way, in sports, you decide to bet on a team through skill research, but nothing is guaranteed as a result, but these definitely increase the chances to a great extent, so you must analyze these things well and make decisions according to your ability. Because in the case of gambling, any result can come at any time. and as a responsible gambler, you always have to accept all type of results.
Luck can change fast result - one match, ten matches. But when we are talking about thousands events - luck will change your win rate for small percent. The main result you will get from your skills.
If your analyze is good - you will win in a long term, with luck or without it - it doesn`t matter.
PS. I hate when someone says "He is lucky". I worked: searched information, analyzed teams, players, etc. And all it work is "just a luck"?
