Yeah what @Jackdee said, plus a million other possible scenarios.
In broad strokes, an active idol conclude her career in 3 general ways, (1) fading: she wants to continue, but there aren't enough job offers to keep her going; (2) moving on: she found a husband/lover, or a real job/business, or accumulated enough money, and leaves the industry for temporary or forever; (3) forced out: outside factor, such as health, accident (e.g. car crash), family crisis (exposed, doxxed), crime, addiction.
Type 2 is easiest, it's common nowadays (social media) that a "happy" retirement is explained. These kind there's a decent chance (I'd say 10-20%?) she might return to JAV, especially if fan support is still strong, and/or she burns up all her savings. So existence of explanation means some chance of return.
Type 1 is most commonly unexplained, partly because it's nothing to be happy/proud of, partly it's lack of fan interest. If there's a lot of fan support/interest/request there's much more likely to get an explanation. Type 1 non-official "retirement" is, I think, quite unlikely to see a return. So no message means lower chance of return.
Type 3 sometimes is explained sometimes not. Because it's neither industry decision, nor idol's own will, the motivation to return is high. If the external factor is resolved, the possibility to return is pretty good. Because of this, even when details/explanations are unavailable, and future is unknown, either the idol herself or the agency would put out some assurance (which really assure nothing, if you read the words carefully) or substance-free message "Don't forget me yet!" which of course tells you nothing and promises nothing. Sometimes the message is as little as "She's fine!" (means she's not dead, yet) or "She has not yet announce retirement formally". But then if even such empty messages are not given that really is UN-promising.
