The chance has always been the same.
Basic games can be called the beginner-friendly gambling game, but this kind of game if we play too much this gives us more enlightenment about getting complicated like what are the possible odds to win this game which is might get riskier to make a decision unlike you didn't totally understand how it works. Even the dice game all you need is to predict the outcome if it's even or odd but of course this becomes more complicated with the use of stats and probability of the outcome of the dice, if you are playing with a dice throw there's a chance you can manipulate the throw but if you are playing dice with the use of randomizer I guess its too hard to win against on it.
Those games are intended to people who are new to gambling or just really do not want to exert time and effort studying a card game or simply a game that takes time to learn. Rock, Paper, and Scissors is also a good example, I've visited several casinos online and have seen games like the dice game and rock, paper, scissors, with just a different user design, and I do agree that these are essential in a casino, one of the reasons on how to maintain your casino is to set up easy-to-learn games like these.
