What I notice also is that most of this seniors could really be rich as they have a lot of people behind them, some could be their grand kids or some could be their maids. Or it could be better if they will just go and stay at home as they could be vulnerable in such places?
My judgement on this will depend on why the senior citizen are at the casino, what's their reason for gambling, was it because they're broke and are in need of money or are they gambling to be active as you said and have fun. Gambling could've been what they love doing when they were younger and now that they're old, they couldn't let go of the old habits. If that's the case then everything is fine althrough we could still look for more exciting activities to do to avoid them associating gambling with fun and eventually getting carried away one day with some bad decision that causes them to get addicted to gambling and they can't stop it anymore. Aged population are into gambling for sure as it isn't just the young adults that are into it but the percentage has to go to the side of the youths.
