Not really because if those newbies can take care of themselves and keep trying to avoid gambling sites, he'll be fine.
But if he tries to trade without doing any analysis he has already started to get involved with that gambling.
But the state of the market has nothing to do with the gambling business and the casino will still do well regardless of what will happen in the market.
And what can attract more members is by doing promotions using various methods.
I will have to agree with you that the state of the market does not affect gambling.
You both are wrong. Many gamblers getting their crypto to gambler from different activities (bounty, faucets and so on). So when market is down, all this activities generates less value, so you have less money to gamble. I doubt that someone you get paid with fiar money, when buying crypto and visit crypto gambling.
