do you think narcissistic parents dont like their childrens to succeed?

I think that narcissistic parents are very contradict somehow because I feel that in one way they want to be their childrens to succeed so that they can brag others about it.But I heard that some parents also feel jealousy or feel afraid about their childern to succeed more because maybe they cannot control them well? I am now very confused about this because my parents show two behaviours in a same time, and could anyone tell their experiences or thoughts about this?
