ELI5: Why does downloading stuff in the background increase my ping (i.e. Downloading a game while playing CSGO causes me to have 100 ping, while not downloading i have 10). How are they related?

Because the packets being sent and received by the download are causing the packet exchange for the game to be delayed.

Think of it like driving to work or school. When there are no other cars on the road it doesn't take nearly as much time to get to your destination. Throw in some traffic, and you'll see it takes a bit longer to get where you're going. The more cars on the road, the longer the delay.
