The expected value is a weighted average of the possible realizations of the random variable (the possible outcomes of the game). Each realization is weighted by its probability. For example, if you play a game where you gain 2$ with probability 1/2 and you lose 1$ with probability 1/2...
E(x) is not the value of the random variable x that you “expect” to observe if you perform the experiment once Interpretation E(x) is a “long run” average; if you perform the experiment many times and observe the random variable x each time, then the average x of these...

The expected expressions are used to specify a test criteria by comparison with the value of a variable. The test receives a passed verdict when the actual obtained value matches the expected value expression.
