Remember that ping often uses gethostbyname system/kernel call where traceroute often uses the actual DNS lookup. You can also easily test whether the entries are indeed in DNS by using nslookup or dig
Yes, ping (and traceroute) use gethostbyname() for resolving hostnames. And gethostbyname() goes to /etc/nsswitch.conf that must have the line
to consider first /etc/hosts then DNS.

hosts
HOSTS(5) BSD File Formats Manual HOSTS(5)NAME
hosts -- host name data base
DESCRIPTION
The hosts file contains information regarding the known hosts on the network. It can be used in conjunction with DNS, and the NIS maps
`hosts.byaddr' and `hosts.byname', as controlled by nsswitch.conf(5). For each host a single line should be present with the following
information:
Internet address
official host name
aliases
Items are separated by any number of blanks and/or tab characters. A ``#'' indicates the beginning of a comment; characters up to the end of
the line are not interpreted by routines which search the file.
This file provides a backup used when the name server is not running. For the name server, it is suggested that only a few addresses be
included in this file. These include addresses for the local interfaces that ifconfig(8) needs at boot time and a few machines on the local
network.
This file may be created from the official host data base maintained at the Network Information Control Center (NIC), though local changes
may be required to bring it up to date regarding unofficial aliases and/or unknown hosts. As the data base maintained at NIC is incomplete,
use of the name server is recommended for sites on the DARPA Internet.
Network addresses are specified in the conventional ``.'' (dot) notation using the inet_addr(3) routine from the Internet address manipula-
tion library, inet(3). Host names may contain any printable character other than a field delimiter, newline, or comment character.
FILES
/etc/hosts The hosts file resides in /etc.

The hosts file format appeared in 4.2BSD.
