Analysis is very important when you are into sports betting. Because that's the only way to have higher chance of winning there and the rest leave it to the whole team/player that you bet. And as you did mentioned dice game, analysis is not really needed on that game and as well as with the luck based games in casino's.
Of course, I can agree with you, but even sometimes our analysis won't give happiness to us. For analyzing, sports betting is a good option because we can easily identify the players and their talent. Because according to their previous matches we can easily analyze how far can we bet on them.
