Do you know what are you talking about?
Do you know what the second level domain is? No, you don't!
.com, .org and .net are TLD = Top Level Domain(s).

As you have no clue
I still wouldn't recommend a .org for gambling though.
As regard to the sale of domain names. You should post this in digital goods.
