Could "luck" increase probability?

No, not exactly.

There are theories out there that when probabilistic events occur all outcomes happen simultaneously yet we are allowed to observe but the one, fragmenting our universe into infinite planes.

If you were some sort of dimensional lord then perhaps you're just picking the outcome where you win constantly, perhaps subconsciously.

A more realistic explanation would be on rooted in implementation of the RNG. Once again, I have no idea how random is generated in EQ land as I haven't looked at the source, but it's possible, depending on your hardware of your machine and other factors that could be used to seed a generator, that your unique combination of credentials could lead to higher rolls on a modulo 100.

Extremely unlikely, but possible.
