Fairly fortunate. If you play through this person's "straight" method for 103 days or until you win, you win with probability 64.48% with an average net winnings of $265.95, while you lose with probability 35.52% with the whole $1990 gone. Overall expected winnings are -$535.27. The probability of winning three times in a row, as you did, is 26.81%.
The expectations assume a prize of $500, as at the link. Your prizes were of different sizes, averaging slightly higher ($520); depending on how these numbers are determined the expectations will vary, but the basics will be the same.

Yes. Each additional game you play causes you to lose money, on average.
