Just based on my own long term observations, the "registered" members are those who sign in to browse and participate on the site. There are a surprising number of registered members who log in, but do not post any content during their frequent visits.
From a previous question of my own, I was informed that the (hidden) or bots have various administrative functions not related to participating in site activity.
If someone visits the site without logging in, they are counted as guests, even if they are actually a registered member. Guests, even registered members who have not logged in, are not able to post content but can only browse the content.
Many visitors only come to learn about topics posted. In some cases, they find a topic on an internet search and come to read that specific content, in other cases, they come back again and again to learn about other sites or money earning opportunities that they have seen discussed in previous visits.
There are many registered members who come back frequently without logging in, including many who have never posted anything at all since joining the site. Those are all counted as guests if they visit without logging in.
