Funny question about not understanding "random".

I play a game online where a random number is generated to determine success of a given action. It is a complicated game, just assume we are talking about hitting a target with a bow based on a number 1 to 100.

I also play a game where a die (actually 2 ten sided dice for 1 to 100 numbers) is rolled to make this same sort of determination when it is needed, by me personally.

In a third game, there is a special tournament rule where a referee has a list of pre-rolled random numbers (using a die in advance of play) and when a die should be rolled, the referee states the number from his list and crosses it off, and proceeds to the next number for the next "roll". This game is really cut throat, and issues with "unfair" dice can break the game in short order.

Assuming the dice used are "fair" in each scenario, the value ranges are the same (1-100) and the random number generator is as fair as the dice, is there any difference between each method of randomly generating numbers?

I ask because I have seen the "random number generator" accused of being biased, yet don't see any bias myself. It seems like a pretty good method of generating numbers to me. The second method of me rolling a die seems to be different, but less "random". Perhaps this is a case of my memory being flawed. The third method seems to be "the worst", because the referee could accidently view a future number and wince or smile, biasing the player into taking ill-advised actions.

Question 2: Could my three different opinions of these random numbers be accurate or it is a poor hunch about what random really is?
