Probability Control System

What would happen when an ordinary man got a system that could control the probability of everything? For example: Rain, probability: 13% -> 100% Earthquake, probability: 0.78% -> 100% Winning Lottery, probability: 0.0000034% -> 100% Awakening Superpower, probability: 0.000...17% -> 100% Earth Exploded, probability: 0.000...23℅ -> 100℅ Universe Big Rip, probability: 0,000......45% -> 100% ... In the Infinite Multiverse, as long there was a probability of it happened, then under the system power, everything could happen! Watch how the protagonist changed from an ordinary man to a figure with an unimaginable power!
