Games based on luck must be supported by experience and skill. In my opinion, experience and skill have a greater chance of winning than losing and are supported by playing very carefully.
You may be able to win in skill-based gambling games because you must have the skills and experience to win. And that might give you a chance to win, so using a lot of money might give you a big win. But if it is a luck-based gambling game, you are relying on luck, where you will not always be lucky.
You are correct once more in regards to skill-based games! You need experience, more experience, and talents. You might get a large win if you have the true talents and a lot of money to invest. However, games that rely on chance? Oh my goodness, its all down to pure luck. Furthermore, I must say that chance is a really complex thing. Regardless of how much money you invest, luck isnt guaranteed. Thus, play it smart and never forget that the important thing is to play it correctly, not how much money you spend. Play smart, play very smart!
