Are you sure about this? If so, can you provide a reference for this? I understand that guitarists can play ambiguous or unambiguous chords. C-E-G would be a Cmajor unambiguous chord even if no bass player is present.
FWIW I think it's the presence of a bass note, played by whomever, that anchors the chord.
AFAICS and major or minor triad is probably unambiguous.
Just about anything else has the potential, at least, to be ambiguous unless that bass note is present.

We have on keyboards, and I presume also on most or all chording instruments, what we call rootless voicings, which rely on someone else, normally the bass player, to supply the anchor for the chords, however it's also not that unusual to play those rootless voicings solo. The effect is of both some ambiguity and some lack of stability, which helps to keep the music evolving.

Whether or not that's what you mean here by ambiguity I'm not sure, but it may be an area to explore.
