That just proves that gambling isn't just about luck, good thinking analysis and skills also matters. But i won't deny that this gambler has also the best of luck since predicting all these results correctly are very rare to happen. I guess in gambling, its not always the house wins. Sometimes, when a gambler has his own unique instinct to win, he will do more than luck just to prove he's something more than that.
Analysis depends too but basically gambling is about luck, especially while staking accumulated matches in just a single bet, it is basically pure luck and nothing more. Although, right thinking and appropriate analyses can help to some level but there are better prediction sites that make few wrong analyses and people that still bet and just lose. If an underdog won a big club, that shows an evidence that gambling is still luck because anyone can lose at anytime.If someone is able to predict correctly the results of 10 matches, why not pick 16? It is simply a matter of probability. Of course, the probability of hitting 16 results is extreme and it is certainly don't hit that often, but it's possible, so I think that's a real win.
The more the matches the more the chance of losing. I remembered a day a brother and his younger brother played bet, they are friend of mine, the brother gave his young brother to play a bet, the brother just added some good matches long, just a match made him lose while his elder brother won the bet of about 11 odds. The lesser the accumulation the more chances to win. 
but it is really a matter of statistics... it had to happen!
