We have been in the crypto gambling space since 2018 we can clearly see that when the market goes down, the activity at the crypto casinos goes up.

Why do you think this is happening?
I don’t really follow the trends around the topic you mentioned but if what you're saying is true my guess is that some traders might be trying to cope with their losses by turning to gambling and spending more time at the crypto casinos . I doubt they'll find over there what they're looking for because
more than often gambling can have the opposite effect just adding more pressure on them.
I would not see the gambling as "a safe haven" at the falling-market-time.
I think explanation is simple. Gambling is an opportunity to get big money in short period of time. When market is down, traders experience loss and they need to close financial gap, they run to casino to recover financial loss with winning money in gambling. Or maybe they gamble because they want to multiply their money to have more funds to buy when assets are on discount on the market.
