Doing sports betting without knowing about the game or without being interested in sports means that you're going to rely solely in luck. I think I would do it. After all, what's the difference when you bet on dice sites that you don't know what would be the output as well. There might be some "science" behind it if you analyze the game but you don't actually understand the game so what's the point of trying to understand the stuffs behind it.
It's just gambling. No need to take it so seriously.
Everything is about luck at the end of the day, but you can reduce luck in sports betting by betting on the usual winner, but it doesn't always work and the odds are always in the higher risk anyway. Its like the Rafa Nadal vs Roger Federer finals, nobody would have guessed that one.
