Only if those backlinks send you some traffic, i.e. if somebody is really reading those articles/pages and clicking on those links. And then, of course, clicking on links at your parking page. Otherwise such backlinks don't matter.
I dont have much time to write long reply as needed but some quick tips
1. check the source of the backlinks, are those sites worth anything
2. if u get the dommain look up how the site was setup back in the day (archive.org) replicate it as close as possible and hope google picks it up again
anyway there is lots more to this art, guys who do this well are very successful
