Please explain how this is significantly different.
Explain how a pair of dice that is "truly random" is different from a pair of dice that is merely random with respect to winning or losing.
There might be a philosophical difference, but not a difference that can be detected by mere mortals.
All the philosophizing is irrelevant, because what experiment shows is that mutation produces all possible combinations of change. Even if mutations occurred in some kind of alphabetical order, the outcome would be the same. Those that are neutral or favorable will show up more frequently in subsequent generations.
If you had an inking of biology, you would know that mutations are not random. As in the output of a dice that has sides numbered 1 to 6, ONLY 1,2,3,4,5,6 are possible outcomes. Nine is not a possibility.
Mutation does NOT produce all possible combinations of change.
Do you have a sense that your casino/dice/gambling metaphors/analogies may be incomplete or even false?
Maybe flesh those metaphors & analogies out a little more.
