Using 'ping' command on Windows CMD, but packet was lost

Today I learned about, basic structure of packet switch mechanism. So I tried a kind of test. Currently I am using Windows, so I opened command prompt, and type ping naver.com, which means send a packet to website https://m.naver.com/. Okay and the result is, **packet: sent=4, received=0, loss=4 (100% loss). And I heard on some website that, if I had my packet loss on specific website, this means, there are problems on network communication between my computer and the website server. But, When I get into the website after ping test, there is nothing wrong on website.

So my Question is this.

1. the meaning of packet loss is the malfunction of network between host and server, but, in my case, it seems to be nothing wrong... Why is it???
