Any one of those games could have (and may yet) reached a critical mass that would lead to profitability, but the market is almost completely unpredictable. Threes was well-designed, simple, and easy to learn, but the moment it hit the market there were a thousand clones (or more like 2048 clones, amirite?). Flappy Bird was a weekend project with "borrowed" artwork and by all rights none of us should even know what it is. There is next to no hope for anyone that doesn't have a massive enough advertising budget to convince people that "hey, all your friends are going to be playing this game, you don't want to miss out." Anything beyond that is blind luck or a truly brilliant/original idea.
