Stats mean a lot overall, but they aren't very good pointers when it comes to skill. Most of the time the team with the most wins win the game. Having more kills in the team points towards a combat advantage. Giving enemies kills = giving the enemy combat advantage. Will the team with the most kills always win? Of course not. Is it a reliable indicator of what team is having combat advantage at the moment? Yes.

About going 1/5 on lane as kat vs fizz, although it is not a sign of a bad player, it is a sign of bad play. Not because you should necessarily have more kills than fizz (since I can kind of see how fizz could be a pain for kat), but because, well, let me explain it like this:

1. No lane (or, well, to be completely certain I should say the overwhelming majority of) matchup has guaranteed kills for either side. Dying is a sign of a poorly executed strategy, whether it was due to not having enough wards or playing too offensively/defensively (we are talking about dying in lane, obviously some deaths have to occur in some teamfights).

2. Even if there is a matchup or a point in time where one side has a "guaranteed" kill, even going to the lane could be seen as a bad strategy, since your resources could be spent on not giving gold to the enemy. You obviously have to weigh the pros and cons of going complete roamer / pusher on another lane, which would be the extreme end of the spectrum as you could always try to farm your lane when your opponent is somewhere else, but if all of your options look grim, then your entire strategy has failed.
