We need to look out how prevalent gambling is in Southeast Asia particularly in Thailand. Thailand seem not to be the top 3 countries on gambling.

For countries that have high prevalence of gambling that has nothing to do with the media. Thailand is a country that tourist like to visit and gambling tourism can be a things just like other things that creates revenue for the government. No movie series can influence it. There is money in gambling and tourist like to gamble even in cruise ships they are casinos on board for people to visit and gamble on. The most customers they'll get are expats who want to gamble and have a good time.
