I have a problem with this being an anti-gambling ad, because the video doesn't share anything educational that would teach people why they shouldn't gamble their entire savings. I couldn't connect with this video, and it might be the same for everyone. Yes, the government may have tried, but I don't think it's enough. This advertisement will attract more people to gambling.
Exactly since at the ending they validated the action of the guy's father who had used all his savings to bet on Germany winning the title, more like saying he took a rewarding risk. If that was supposed to be an anti-gambling add, then it defeated its real purpose. A neutral person would drive inspiration from the action and replicate such irrational gambling practice.
But yes, everyone has their own perspective and there may be differences in how they view things from that perspective.
Just maybe, but almost everyone here has problem with the plot of the ad, this would give you insight on how the audience it was meant for viewed it too.
