Alcohol, substance, and gambling addictions, they all sometimes contribute to aggressive behavior of the person, behaviors, and decisions that could ruin their lives or others'. It is not limited to gambling addiction alone.
From the article shared by the OP, the 65-year-old grandfather could be in deep gambling addiction; he would never do what he has done if not.
It is not age limited but quite dangerous for underage gamblers who have been targets for some online gambling platforms years ago before proper regulation requirements. The addicted gambler can lose control over his emotions and gamble with the money he can't afford to lose. That is why there are so many beggars on casino chats looking for free tips after losing rent money on useless slots. It is what it is and only hard life lessons may change their perception of this industry, IMHO.
