If I should win a huge amount, I would use it to complete my Education & also upgrade my skills since these are areas I'm poor at. Gambling doesn't make you rich until you hit a Jackpot 
Even hitting a 'jackpot' wont make most break even and then they're even more addicted because they're chasing that big win again.
makes senses to walk away from gambling should you ever win enough. you have the right idea with education.
