You are, in effect, trying to solve several problems at once:

Generate a random number with the distribution you want.

Pick a new number at program-appropriate times.

Display text on the ball.

Change the text at program-appropriate times.

Move the ball according to a chosen number.

If I were trying to do this I would break it down into small pieces like
this, and work on each one of them separately. If I did not already know
how to do one of the things, I would first test it in a very small,
simple program.

Testing the rest of the code is much easier if you are not playing with
random numbers during the test. With random choice, you cannot tell if
the number failed to change due to a bug, or because two consecutive
spins of the random number generator got the same answer.

You would be much less likely to get stuck doing it that way. If you did
get stuck, you would have an SSCCE you could post when asking about a
specific problem.
