Zoom is good at filtering out rather loud background noises. I can't imagine that the sound of background typing during a conversation could be detected by the other party.

What? Zoom (by default with auto mic adjustment) catches everything. Typing on laptop is especially bad as it is closer to the mic than the person speaking (unless there is external mic), so it's like a stampede of rhinos.
