ELI5: Why when my heart beats fast from playing games like League of Legends is it considered unhealthy, but an accelerated heart rate from exercise is healthy?

The increased heart rate isn't particularly healthy for you, its just an indication that you're working hard. Its like the RPM gauge in a car. If you're in neutral, and your engines racing, its not a good thing, but if you're accelerating to get into the highway, its a good thing for your engine to be spinning quickly.
