How is this site well ranked?

I started a new site (online movie site and series) and bought an expired .com domain.
My domain has reasonable metrics but what happens is that so far I have not understood why a domain occupies the top positions of Google on multiple keywords and has lower metrics than other competitors.
The site is .pro. According to the semrush of the 53k of backlinks, 49k are from the same domain.
90% of the rest are backlinks from sites like similar sites, Chinese websites and so on.
Why is it better ranked than other sites with higher quality metrics and backlinks?

Is it very difficult to pass it to the SERP?
Looking at my domain metric, can I pass it on the SERP?
Let's have more or less the same content.
My site is still under development.
I know the metrics of moz, majestic, semrush, ahrefs and etc ... are different from Google.

What about the site age? It also plays a big part in ranking. Also perhaps that other site is using PBN links and hiding it from link crawlers?

Because your domain is expired and google knows it
