As in many AIBU, the “neggers” soon come along to make the OP wrong or to blame, without any rationale or evidence. Try to ignore them OP.
The only evidence we have is what the OP has said, which is that she
(a) is applying traditional dinner-party conversational rules about individuals conversing with individual neighbours to a big, collective family Zoom call in which the technology means only one person can talk at once, where they simply don't translate
(b) is also applying very old-fashioned and highly gendered ideas of 'good manners' meaning she believes it is correct to talk little about yourself unless someone asks a direct question
(c) by her own internalised code of good manners, she is therefore doing her bit by asking about the other people's activities, and believing that she is inviting reciprocal questions, and is seething because they aren't operating off the same rule book.
It's hardly unreasonable to point out that not everyone has her internalised code of 'manners', and that if she wants to be less annoyed, she probably needs to alter her behaviour, because she can't alter theirs. Or have Zoom calls with fewer people at the same time.
It is certainly perfectly possible that never talking about her own stuff and her family's stuff is being interpreted by others on the call as that she wants them to talk if she keeps asking about them. I know some people at the moment are just saying 'Look, literally nothing has happened to us since we last spoke!' I'm certainly talking about books or music to friends rather than about my personal life.
