Depend son how you look at things

Take a bag filled with 100 marbles
20 black 80 red
pull one out

you have a 20% chance of pulling a black.

Now if its red leave it out
and pull again.
The chance is no longer 20% to pull a black.

SO you have to put the red back in and pull again to make the chance 20%.

The chance of success of one attempt is not associated with another in any way shape or form. The % shown is for one individual attempt not cumulative or to succeed to get to the next saint level.

Stack your cards instead of doing 30 attempts with 1 card at 20%.

Because imagine a bag of 10k marbles with 2k black and 8k red marbles. The % is still 20% to get a black. but there are 8k ways for you to get a red
