"Top talent" is probably the wrong way to look at this, because it's only a relevant label in the context of (broad) role and level of seniority. Almost noone in any given company is truly indispensable, and employers may not feel the need to retain even top talent at some levels and in some roles because those roles just aren't that important or they don't view them as needing "top talent" to perform. I think the term "key person" is probably more helpful - you can be a key person (and thus your employer might go out of their way to retain you) without necessarily being "top talent" by virtue of eg being uniquely qualified, in a position where it would be disruptive/expensive to replace you, etc.
