Maybe life sentence, but even the Chinese drug boss that has been caught or any other criminals for that matter could get out. So the justice system is not that strong in the Philippines from what I read, so it might really take time to see the results or even if we see the big names right now going to jail like the former Mayor of a town who is accused of being a Chinese spy, as she is the own who facilitated POGO's in his town and obviously, she is the protector.
They abolished the death penalty, then reintroduced it, then abolished it again. By the way, some politicians are in favor of the death penalty. All your arguments perfectly demonstrate that the real problem of the Philippines is not gambling, but the high level of corruption and the inability of the government to resist crime. In my opinion they just need to raise the standard of living of the population. Without that, the problem cannot be solved. We all know that many laws can be easily circumvented and banning gambling is one of them.
