There are lots of things in the news that some people don't care about - they report on traffic (or at least they used to) even though many people don't commute. They report on the stock market even though many people aren't invested. These days they sometimes report on Bitcoin and other crypto, even though the vast majority of the world has no interest. Speaking of the world, they report on world news that most people don't care about, because they're only interested in their own country.
The news reports on things that people care about. A lot of people care greatly about sports. Just because you're not one of them doesn't mean it's strange to report on them.
