This is fairly normal and common, especially if you browse without aggressive ad blocking.

I routinely see a single ad impression make over 20-50 connections outbound, and repeatedly close and reopen or randomly open new ones for various reasons, the most common being some form of "anti ad fraud" tracking that repeatedly polls to get an average or median latency, new connections and requests firing on every mouse move, etc.

Would also be entirely unsurprised if phones that had free mobile games and equivalent were polling and sending stuff like location data every minute.
