How is it different than the program just choosing the number it wants within range?

Simples RNG works as follows:
1. take a number between 0 and 1, with lots of decimals.
2. Multiply by a really large number
3. Keep the decimals, drop the integer part (e.g. 123.4567 becomes 0.4567)
4. You have another number between 0 and 1, and there is no easy way to predict its range if number in step 2 was indeed large.
5. if you want more random numbers, take the number from step 4 and use it to repeat steps 2-3.
NUmber from step 1 is the “seed”. Same seed means same sequence of “random” numbers. Which is useful for debugging. For a truly random choice of seed, take system clock and use it decimals from seconds counter.
