Not usual but it can happen, 40 red losing streaks are something that you can't imagine happening if you are the one who's playing, those who are using martingale system who hopes that they can recover their losses after winning their next bet would be empty if that long losing streak take place.
That's why the Martingale strategy requires big money when you really face a losing streak of more than 20x, let alone having to lose 40x in a row, that's definitely a big loss and drains all of our money, that's why I never really believe in dice or casino games others are called "Probably Fair", but again it's up to the gamblers how they stop playing before the dealer drains your money.
Never be tempted by big money targets, always enjoy the results you get, you don't need to be big, at least win a little, as long as you are consistent, that's more than enough, even though I can't do that, I think other people might be able to do it, as long as they are consistent with small achievements, that's enough .
