You can lost everything if you gamble with a lot of money on risky gambles. The best way to gamble on sports is to put a lot of tickets with not much money.
i do not think that gambling is risky if you are expert in gambling then you will never lost your money there is many people join gambling without experience they lost their all money.
but to me i think in most of the gambling game your experience and your gambling skill cannot work, as in most of the gambling games e mostly depend on our luck therefore your experience and your gambling skill do not work here, so if you are luck then you can certainly make good money in gambling but if you are not lucky then you cannot make money at all.
