The first major reason for CS2's low scores is the gameplay itself. A lot of bugs and glitches have frustrated gamers of all skill levels. A lot of game modes and content from CS:GO have also been removed and many players feel CS2 is “unfinished” and lacking content.

The easiest way to do this is to play on Deathmatch free-for-all, as you'll have plenty of targets to take out. Plus, if you play against bots, then any reasonably skilled human player will be able to get the kills easily. Once you've got the kill, just play out the match until the end and you'll get the achievement.
