It's been 2 years since public PR was last updated so the questions you need to ask yourself are:

1. Do those 2 backlinks actually have their own supporting followed backlink profiles? PR is created from other authority pages on the net with followed backlinks.
2. Do the 2 backlink pages have 100s of followed outbound links pointing to other domains? Webpages with 100s of followed outbound links will reduce the SEO value of a followed backlink.
3. Do the 2 backlinks have 301 or 302 redirects anywhere on the Wayback history. An old PR sellers scam for faking PR is doing a 301/302 redirect, wait for Google to update public PR, remove the redirect/s & sell fake PR links. Those fake PR links are still out there because the last batch during the last public PR update in 2013 would have never been updated for the public.

PR can still be an indicator that a link is potentially useful for SEO but you still have to do the research & prove the link is legit, otherwise you're just guessing..

If both the links from PBNs then check the present status of them.

I would suggest getting some quality backlinks from guest posting from authority sites will help you a lot.

SEO is always a long term game, you can not expect 2 links will do all magic.
