Every gambler has his/her own strategy in gambling that gamblers want to earn profit by gambling. Gambling generally has many categories here the gambler confirms in which category he will gamble. There are some gamblers who always prefer sports betting to gamble while there are some gamblers who prefer to play casino games. But I have always preferred those categories of gambling that I have an understanding of and where I can apply some of my skills. Gambling cannot be done entirely on luck then only money will be lost from here on out. We should gamble on related things that we know about and that we can predict to some extent before gambling. Gambling in this category shows that by applying luck as well as skill, we can be somewhat confident about the outcome.
But every strategy in gambling is just way for gamblers to have confidence in their bets, their skills and also their expertise in analyzing to predicting what will be bet, of course this will not provide any guarantee for someone to get win.
In general, gambler will have full confidence in the strategy they have to be able to achieve success in betting or playing, on average every gambler also has the option of their pleasure to choose casino game or sports betting that can make it easier for to win.
But it cannot be denied that in gambling don't have to rely entirely on luck because there are several choices that can really rely on skills and knowledge, but we must remember that the dealer advantage can never be surpassed by using any strategy except with luck.
I agree with you about the strategy, it can be said that it is the capital they have to be able to make them confident in gambling. When players come to bet, of course most of them have a strategy that has been prepared, so they will feel confident with the strategy they have to be able to make them win, and with their skills or expertise as you said it also helps them in increasing their self-confidence but it should be noted that being too confident is not good.
You are right, although some games are based on skill, the advantage that the dealer has cannot be surpassed by players who even though they walk bravely feeling confident with the strategy they have, it will not be able to fully make the player win because the dealer has more power in this matter.
