it is impossible for a country without laws regarding gambling to allow online gambling in their country, this actually happens in my country too, our country's government strictly prohibits gambling but does not really regulate it in law so many people still gamble in secret.
In countries that have laws regarding gambling and regulate it in their laws, business owners and gambling players get tax benefits, while in countries that are still gray about gambling, usually players only play in secret and gambling business owners are almost undetectable.
