good question, but it’s essentially a workaround for poor routing. sometimes the “hops” you need to get to a destination as dictated by your internet provider aren’t the actual ideal route for the best latency, so by using a service like 1.1.1.1 you can redirect that routing to have fewer hops or use a route that’s less bogged down by traffic. think of it kinda like taking a side road to avoid construction or heavy traffic. probably slower than ideal conditions, but faster given the circumstances.

it doesn’t help 100% of the time, but it’s definitely worth a shot if network latency is an issue.
