Hi PeterTee,
I'm mainly an online cash game player so I don't have much experience with live tournaments. If you would have asked about online cash, I would have said that if your winrate is 2bb/100 over 200k hands, you could start to consider yourself a winning player. That is some kind of a rule I have heard a long time ago.
Now, when it comes to tournaments, I believe those are even a bit more variance heavy and you really need to play a lot. As Kyyberi said above, 100 tournaments would be just nothing, like a grain of sand in a desert almost.
Okay I guess your results could give some clues too. If you play just 100 tournaments and manage to final table half of them, maybe you are a decent player 
However, if you just started out, my best guess is that you are not yet a profitable player. Poker is a bit difficult game sometimes and it really requires a lot of practice at the tables ( which you won't get much when playing live ) and it takes a lot of studying.
Here are some questions that I think even a slightly winning player should be able to answer:
1) do you have any idea what hands you should be opening pre-flop on each position?
2) do you have a rough idea what hands you should be defending vs raises from different positions?
The answers don't need to be super specific, I just want to make sure you know that the ranges should be a bit different and you have some idea how to play.
3) do you know what pot odds, implied odds and reverse implied odds are?
4) do you have a basic idea about how to size your bets?
5) do you know when you should switch to push or fold strategy?
6) do you know why defending and stealing blinds is very important?
Now, if you can think of an answer to those questions, it is good. But if you have absolutely no idea what I'm talking about, there is a good chance that your results so far are based just on luck and you can't be profitable on the long run because you simply don't know how to play yet 
And if you don't know the answers yet, don't worry. Just browse this poker site, read the strategy articles, watch coaching videos and participate in the hand discussions and you will learn a lot.
