I play over 10 years.
I have been playing for 10 years and I will tell you that the above methods work. But there are no systems (except for counting cards in Blackjack or playing poker). For me, casino is entertainment, not very often practicing entertainment. I never thought that I can make money at the casino and I won't think so. I set strong limits, I don't take ATM cards to the casino, I go in with the cash I want to lose and have fun at the same time. Will it succeed? COOL! But I won't be back the next day or the next day or next week. You break these rules, you're a loser. Casino is entertainment that should not be practiced too often.
