If you can't take any risk then you can't fight with inflation because if you keep your money without investing than over the time, you're money value will reduce. So you should find suitable investment products to grow your money. Of course, gambling is not an investment, but it is just a paid games to enjoy your free time.
Even if you have skills on trading its still not risk free since risk free word means %100 and remember every investment has chance on lossing up your money. I do agree gambling and trading somehow the same on the risk on lossing but in trading you could lessen the risk if you trade smartly unlike on gambling its a totaly blind gaming.
