There should be a specific audience or target, but as i can see even the young saw gambling ads, there should be a specific target, like if the user is under age, he/she should not see any gambling ads, only the adult should see it, when it comes to tv commercials we cant do anything to set those rules, but it is better for the gambling ads to be put on a place where children are less visible that is just my opinion.
I'm one of those people who no longer likes watching TV, and it's been a while since I've watched it. I get my news, entertainment, and other things from social media, so I don't really know if there are gambling ads on TV shows like sports, like football, basketball, or other shows. But what I see on social media is that gambling ads are always present. Whether it's on Facebook, Instagram, or other platforms, I always find them, including when watching live football matches.
Gambling ads on social media might not be obvious to minors, but if they were on TV, I think they could see them. Furthermore, many minors are now using social media, so I think it's not unusual for them to see gambling ads.
