Is using the Google Public DNS as safe as I hear it is?

I want my Nintendo Switch to run faster while playing online because I always find I have terrible lag spikes during online smash matches. When I looked up ways to boost WiFi speed, I came across the Google Public DNS and people saying how fast it is. The only thing that really irked me about it was that it said “public.” Not really sure whether it’s safe or not and looking up whether it is or not just gives me vague answers, so I though Reddit could help out. Is Google Public DNS safe and I am I more vulnerable to getting my compromised or hacked by using it?
