Given that the only reason that countries tend to ban gambling are usually religion related, it might be a bit hypocritical if they were to allow universities or educational centers to teach people on the topic. Not sure they could justify a "we claim God doesn't allow it, but we'll teach you how to do it if you want to practice it elsewhere". However it's possible they can do things to work around this, if you think that let's say 70 or even 90% of what's required to run a business is universal, they could teach that and then students might do a "finishing course" in a different country that specializes in the gambling industry. I'm not sure any educational institution would want to get involved in this area in conservative countries though and the leadership are often staunch supporters of government policies.
