I've always found those statistics to be a bit odd, given how popular other languages are, especially the likes of Python.
Not only that, but since .NET Core and the new versions of .NET running just fine on Linux distros, I'd expect their usage to go up, not down.

I've spent 15 years writing serious code and never ran into Python all that much until I went back to engineering school. I don't think a lot of people use it for their backend code, at least in my experience. But wow are there lots of stats and science people using it exclusively--it's completely ubiquitous in academia and research (though R is making headway).
Second that, PHP is still default for hosting providers. I get basic hosting for free on OVH with domain that has PHP by default. So even if I am .net dev on my job I still have some personal stuff in PHP because it is default and I cannot change it for that managed hosting env.
At my previous job, we had micro services in Java that did most of the work. The frontend was a thin layer of PHP that focused on SSR, but PHP is the only detectable tech from the outside
