It may worth adding that usually in computer science
pseudo-random numbers are generated. Truly random (?) values are only to be
found in nature. And pseudo-randomness may, strangely(?), be closer to what you expect in statistics.
In my computer programming class, we're task to random out numbers and sometimes, tutorials are saying that random numbers mostly comes from the current time you have in your computer's clock. In this case, the system is basing the random number which is not actually random at all. Applying it to the context of gambling, random chances could possibly have a basis of it being random and might not be random at all.
