I am assuming this is just for fun, but in case people are looking some confirmation from these results, i need to say that the reason why martingale doesn't work can be proven by mathematics.
You can't really draw any conclusions about statistics by gambling on few games, because statistics require a ton of data and results contain margin or error.
Exactly, no matter how you try to put it the math ends up pointing at probability. You are still luck dependent either way. The thing is those so called stats only gives you a measure of what should play out if it goes strictly mathematical but the big problem is bets don't depend on math only but luck too and luck can't be predicted.
Take a coin flip for example, math suggests that for every 2 flips you should get a had and a tail. But the thing is based on luck you could hit heads 10 times in 10 flips even if the chances is around 2
-10.
