so, anyone can tell me, am i qualified to be mathematician?
No (no one here can tell you, except perhaps yourself).
T_T, i can't be mathematician then.
Are you seriously taking the advice of one anonymous person on an Internet forum and basing your perception of yourself upon that? Unless I'm not detecting some kind of sarcasm, you really need to learn to do some personal introspection instead of relying on others to tell you what you can do (no matter whether they agree or disagree with you). And by the way you made this inference. humanino never said you weren't cut out for math just that linear algebra and probability are beautiful.
or maybe mathematician that majoring in calculus.. is there any?
AFAIK there is no such thing as calculus is really just a mix of a lot of foundational aspects of other branches; mainly from analysis.
You do not yet have the experience to tell whether you like linear algebra, or whether calculus is really your favorite subject. You may find that algebra is more of your thing, or topology, or functional analysis. I would definitely not give up yet. Probability is mostly an applied field whose pure counterpart I guess is something like measure theory, and to be honest very little beyond pretty trivial matrix theory feature in advanced mathematics (sometimes we discuss structures that can be described by matrices, but we often don't as we don't need to).
I assume you are/have just taken an introductory linear algebra course. Personally I didn't like that either. Introductory linear algebra is so far the only math course I didn't like. It felt like we were back in middle school doing arithmetic just with blocks of numbers. It felt like the focus was on very concrete structures and we very for some reason afraid to generalize even when it simplified the situation. I have however come to at least like it somewhat after learning more advanced mathematics and learning the more abstract parts of linear algebra. I suspect the reason standard introductory linear algebra courses have such a focus on matrices, finite subspace of R^n, algorithms, etc. is that they need to be digestible by people who haven't acquired the mathematical sophistication yet to appreciate the underlying math except through examples. Personally I feels this spoils the subject somewhat, and remembering how to form change of base matrices, construct inverse matrices, solve systems of complex linear equations, etc. is pretty pointless. After doing some abstract algebra and dabbling in some representation theory however I see that linear algebra can be beautiful, it just isn't as presented to freshmen.
For me the lack of abstractness was what made the subject though, but I know that for other people what made it though was too much abstractness. In my opinion these people will have a harder time later on, but I have seen plenty of people struggle at the beginning only to come out near the top later on.
