ELI5: How does toilet paper not become damp from the steam produced by a shower?

TLDR: Your shower doesn't produce THAT much moisture, and it doesn't last long enough to cause considerable damage.

Basically paper has to be splashed with water or soaked in it to get damp. Moisture in the air isn't enough for paper to get what we would consider damp.

Just looked this up on a few sites talking about archiving paper. Even at 100% humidity and room temperature paper only absorbs about 20% moisture content. That's enough to start causing curling but not enough to get it wet.

Generally speaking a shower wouldn't be enough to cause this on it's own. You are more likely to get paper damaged by water if you live in an area that has 100% air humidity on a regular basis.
