RNG -  Random Number Generator. Whenever we pull, the game generates a random number which determines what arcana we'll get. While I do not know how Chain Chronicle's RNG system is exactly, here's an example:

Let's say that for a pull, the game will generate 2 numbers: one for the rarity roll and one for the arcana roll. UR rate is 7% so let's have 100 numbers and assign numbers 94 to 100 to be UR. There are 5 URs in the pool so let's assign numbers 1-20 to Ronda. A player draws and the game will give generate numbers randomly. Say the numbers were 96 and 27. The player will get a UR but it will not be Ronda. If the numbers were 100 and 2, then the player will get Ronda. If the numbers were 27 and 94, then the player will not get a UR.

The player cannot control the RNG, at least directly through normal gameplay. "Perhaps" it can be set to a certain instance like people suggesting to reset the game and such but until definitive proof (like copy of the game code or thousands of samples run), they are attributed to "luck".
