The many consecutive losses may look unrealistic at first impression, but it becomes quite often because gamblers need hundreds or thousands of bets to make some decent profit with a low base bet as many faucets/free bitcoin sites' users are used to play. The less money the person has, the more greedy he becomes to double this amount through low bets, but really frequently. Then it becomes a dangerous journey and high loss streaks are hit often.
That's right, we are talking about people who wager 10 satoshi base bet, and when they earn they earn 10 satoshi, which is not a lot and they would need insane amount of wins in order to make it actually worth something. However if they are on a losing streak its 10-20-40-80-160-320-640-1280-2560-5120-10240-20480-40960-81920-163840-327680-655360 and goes on. As you can see this already gave you tens of thousands of dollars worth of loss and it was simply 17 loss streak, from a mere 10 satoshi which is nothing to tens of thousands of dollars on a 17 loss streak. I have to say 17 loss streak could very easily happen, could go as much as 20+ as well but didn't see the need this explains everything, and anyone who thinks "17 in a row can't happen, that is a low chance" doesn't realize that it is quite common when you play 10k+ amounts of dice back to back in one session.
