Describe the feature

Looking at this PR: #6406

I see we have 100 results for math.random() with no arguments, which returns a float between 0-1, which we typically are multiplying by 100 and then flooring.

We have 4 results for the regex: random\(\d\).

I think we should be using math.random(1, 100) in pretty much every case, unless we're picking from a container, matching onto stats, etc.
