Video poker is not a real poker.
Martingale is a guaranteed winning strategy only under two small conditions: 1 - there are no bet limits, 2 - you have an unlimited amount of money.
So basically if the central banks started using Martingale then they would be able to win

Then I would say the casino owners will cry on this as they keep winning, so they ain't going to get any profit. I don't also agree on the Martingale strategy (
well, it can slightly increase your winning percentage, but it's not guaranteed), since even if you have unlimited money and bet, if you sum up all of your losses and cross-check your winnings, it will be still a loss. If there is a 100% winning strategy in gambling, for sure, no casino owners will be building it if they are just giving away free money.
Martingale does not change your odds or slightly increase your winning percentage. The belief that your odds improve by doubling your bet on the same bet that you previously lost until you win is nothing more than a fallacy. The way you have described it is also totally inaccurate.
