What happens at 0% or 100% probability?

At 0%, the result will always be False; at 100%, it will always be True — the probability directly controls the likelihood of each outcome.

Is this the same as a coin flip?

At 50% probability, yes — it behaves identically to a fair coin flip, but you can adjust the probability away from 50% to simulate weighted/unfair outcomes.
