Ping-attack on a server?

Ok, following might be a stupid question but since I’m really new to hacking and cyber security stuff and I’m just thinking about how an attack on a website might look like, I’m gonna ask this:

What if you would use a very high amount of machines (for example a botnet) and run a ton of “ping” processes on them, all pinging one webserver at the same time, could this actually take down the server or massively interfere with its regular operation?

And is this already concidered a ddos attack, since I am trying to get the server down with a lot of “attackers”?
