In my view, those issues could add up to the problem, but it is not necessarily general. I heard stories about wealthy people with families to lose basically everything gambling. There are many aspects, and every situation can differ a bit.
Everything may happen, as most of the people say in our country, life will surprise you. There are a lot of rich people addicted to gambling but I don't think it will come to a time that they will be losing it.
Most of the rich people has a lot of investments, lots of sources of income so I don't think losing some money on gambling will eat that all up unless they are really addicted or into it.
