Yes. That's how evolution works. Your genes are randomized during life/mating.

Due to selection pressure one variation is favored over the other. That's evolution.

So in evolutionary response to poachers elephants evolve no tusks.

Evolution is not a process by which beneficial genes are created, it's one where they are filtered for.

Across thousands of baby elephants there are a likely hundreds of unique genetic differences. Most are worthless, some are detrimental, and some of beneficial. Evolution is just the process by which the beneficial ones thrive.

(Noone thinks that "getting born" involves intelligence choosing, the point you are repeating applies sometimes, but here out of context imo.)
