Yes, this is about Coinbase wallet. They simply blocked my wallet from further usage just because I received some funds from a gambling site's wallet but I recovered my funds by deleting the account permanently so I got some luck though.

But it may not happen with every user so make sure you deposit funds to you wallet if you are sending from any gambling sites.
