Such stories are very inspiring! But as you know, these are isolated cases in a million.
Yes, but if you keep trying, it you could be one of the lucky winners that will be listed in the history. 
Most of the time you will lose, but just don't count your loses, keep betting and keep hoping one day you'll hit big time win.
That's the only strategy as you are mostly relying on luck here.
But I just hope no people will ever be caught in these isolated case, what I mean by caught is this-- people who are really into betting to hit this jackpot even though sacrificing their own normal life. Using money meant for other things. Spending and selling their properties just to afford betting. Its alright wishing for the jackpot. Try and try as long as you are still using your spare cash.
Keep betting but make sure you ain't using your other money because you are so caught up in winning. What will it take if you just lost all you have but the one time jackpot you heard from other didn't come. And yep, its luck.
