If there is a 10% chance of losing all the stake, then it is gambling. In my opinion, I mean... there are casino games like dices in which you are allowed with mess up with the multiplier in order to get even lower chances of losing and it is still gambling, isn't it?

Only if the chances of losing are specially low, like down to 0.0001% I would say it is not gambling. Otherwise, investing would be called gambling and going to work in the morning would be considered to be a form of gambling as well, both of those activities involve a degree of risk, not only of losing one's money, there are also statistics on how possible it is for one to lose one's life in a car crash. In life there is risk everywhere, but not gambling.
