Clarification?

Your first assumption is correct: stars in the same constellation
merely happen to be positioned in approximately the same direction
from us. They can be at any distance from us. And their distances
do vary widely -- consider for instance the Summer Triangle, where
Deneb is approx. 100 times farther away than Vega or Altair. OK
the Summer Triangle is not a constellation, it is a large asterism,
but we use it frequently to orient ourselves in the sky, so the
same principle applies.
