There are so many disadvantages of being so addicted in gambling, one of which is forgetting your priority, spending your time to your family and your friend, you won't be able to more productive things than losing money, to the point that even you already lose and don't have enough money to play, you will make ways, there are times that you will ask a request to your friend to give you money as debt. You should be the one who controls the gamble and don't let the gamble control you.
It depends on what type of games you're playing.
If you play poker or sport betting for example you'll not systematically lose money. If you have good skills for them, you can even win money.
Depends also what cards you get because yes poker or other games needs skills before you win because they have many combination and a player to learn about different techniques on how to win.
But trully that once a player is addicted is many of them are forget what they need to do first or their priority because the only need they think is play gambling and using more money even that is use for their needs they still playing that become threat to you and family of the player.
