No. You need to link your Google adsense account with hubpages in Setting section of the hubpages. You just need to login to your adsense account and accept the association of hubpages. Then you can start earning in your adsense account for your hubpages site.
ohh. You have 98 hubs!! Still You have not linked your adsense account with hubpages?
I would suggest you to link it immediately. If you don't have adsense account then apply for it. You will be approved immediately.
