Maybe you didn't know but all other videogames with RNG have these secret tweaks and extra calculations that go unnoticed.
That's why most won't show or discuss their maths. Xcom a huge game in the TB genre I believe does some voodoo to make the gameplay better to what the players expect.
Honestly, pure RNG often causes people to think the RNG is broken because they're getting the same result so many times in a row for example. But that is how RNG works. If the game has hidden math to reduce chances of lucky / unlucky streaks, players tend to think it's more accurate to what it should be (not knowing what's going on under the hood, just knowing the results)
