You are mixing together statistical mean with variance. You can have a mean of 10 but still a worst case of 1000. Variance defines how broad the spectrum of outcomes can be, and spoiler, gambling and system that are build on similar mathematical principals have high variance so you end up with a lot fast winners and a few that get screwed over really hard. This way you have the positive effect that a lot of people won't believe you, when you claim you needed 1000 runs to get a item which others get in 3-10 runs.

So if you ask for guarantee when it comes to RNG based system, then you haven't understood the basic mathematical model of gambling yet :-)
