What you say is true, no matter how we try, even if it is based on instructions from experienced gamblers, if we don't have luck in gambling then there will be no winnings to be had. because in any gambling game, in my opinion, winning is based on luck, including gambling that is based on skill to be able to play it.
In fact, not everyone believes in what luck is because they will definitely think that their winnings are purely due to their own skills and learning from their own experience, even though it is actually luck that gives them victory, many do not understand the concept of Luck and Bad Luck in gamblers, as For example, if a person gambles and wins, it is luck for him and for someone who loses at gambling, it is bad luck for him, but that is just an expression and proverb in my view because we cannot define in detail what true luck is, but we know that all wins cannot be separated from the luck I mentioned earlier.
All gambling requires a lot of experience and skill because it is only a starting point to strengthen the bet and in order to win because basically the result is still luck too, maybe we can just take an example, for example, or say when we bet on sports betting where the team is the strongest. losing to a bottom team can be said to be luck for the winner and betting on an underdog or bottom team, in contrast to when you bet on a top team or favorite team you may experience bad luck and defeat.
