I dont believe that only luck will favor you all the time. if so then I should say that luckiest people should also be the wealthiest people in the world, but nothing is like that. It means that gambling doesnt depend only on luck and some other factors also necessary in gambling, like gambling skills, tactics, bluffing, tricks etc. having these qualities you will be a successful gambler.
Stop playing hide and seek with reality bro, there is no form of skills tactics or tricks that will make you successful in gambling. It is all about the luck and that is all. Even if you want to apply some skills, with most part of it you are still making blind decisions with an expectation for the best, but if you get yourself so much in that mindset and anticipation for the winnings when it comes to gambling, you will get screwed pretty fast that you will eventually hate yourself for it.
What the OP said sounds realistic, and it is always better for anyone to at least, try as much as possible to have the mindset that would help them control their impulses when it comes to gambling.
