While playing poker counting the cards is also similar to make analysis about the game, in sports betting we have to make analysis to predict about the sports on that we are going to place bet, in luck based games much hard to predict even with graphs.
Example of luck based games is Dice. Using analysis on this game is just a waste of time for me, because every rolls that they are making are random, so there is now way that you can predict those rolls for you to win, maybe you can, if there are patterns that they are using but there is not. That is why every rolls that every players will make in this games, they always says "Win, win, win, win", and this is the word I always says whenever I'm gambling. I've never try poker, it is too hard for me to understand the rules.
What you can do with dice is just to limit your bankroll, the chances we have are low compared to the house so it is expected that we will lose in the long run. Those who last are really those who loves to take risk, it's a complete gambling that is based on luck. The longer you play, your chances gets lower. As I can see, there are some big rollers who bet more than 1 BTC, I guess you would have a good chance to win if you have a big bankroll and just play a limited time or else have a target and if you reach it, you will have to stop no matter what.
