Basic misunderstanding of international law on your part. A "service", website, or software program is considered to take place where the user is located, not where the website is located. This standard was set decades ago (in relation to services) and extends quite well to websites. Thus, the gambling in your example would be treated by international law as occuring in NY. Moreover, by choosing to do business with NY residents (unless such business is minor or incidental), the gambling websites would be subjecting themselves to the jurisdiction of NY for criminal law purposes).
