No I think there will be some spectators but not in the usual sense. Anyone thats in the bubble should (I think) be allowed to sit in the stands whenever someone is skating ie other skaters, opening cermony skaters, coaches and other staff/media people.Will there be 0 spectators?
But the stands are huge and even if up to 100people will sit and watch the competition in the stands it will probably still feel verry empty.
