Answer 1

For gaming & gambling purposes, it doesn’t matter if a number is truly random or pseudorandom. All that matters is that they are unpredictable and have no distribution bias.
Both are relatively easy to achieve by using seed numbers that no external user could possibly have access to, such as the host computer’s clock or temperature sensors (or both concurrently).
