From wikipedia:
A Mary Sue (sometimes just Sue), in fanfiction, is a fictional character with overly idealized and hackneyed mannerisms, lacking noteworthy flaws, and primarily functioning as a wish-fulfillment fantasy for the author or reader. Perhaps the single underlying feature of all characters described as "Mary Sues" is that they are too ostentatious for the audience's taste, or that the author seems to favor the character too highly. The author may seem to push how exceptional and wonderful the "Mary Sue" character is on his or her audience, sometimes leading the audience to dislike or even resent the character fairly quickly; such a character could be described as an "author's pet".
Yang Guo is a kid who enjoys making entertainment for himself, possibly because he has been outside society for much of his life. Not in the Zhang Wuji sense of living in the wilderness, but living on the edges of society, yet excluded from it. A similar character would be the protagonist in Grave of the Fireflies, but Yang Guo has evidently managed to scratch out a living, unlike the Fireflies character. There are a number of character traits associated with this, such as selfishness (necessary for survival), self-centredness (outside society, he is the only person he knows), shallowness (there is no structure in his life), and probably spitefulness (a desire to be avenged for the beatings he'll have taken in stealing to make a living). Because of his life outside society, he is intensely grateful to those who show him affection, and love and gratitude form the basis of his view of society. Aside from his upbringing, add intelligence and the occasional spark of unselfishness, even to the point of heroism.
Is Yang Guo such an unrealistic character? He's a cocky brat, although as far from spoiled as can be. He has some qualities on top of that, but his brattishness shows throughout, as a not unrealistic consequence of his early life. After his epiphany, he manages to turn that brattishness into qualities of their own. But those qualities are still traceable back to the brattish Yang Guo we see in his first appearance.
I won't defend the unbelievably bland and badly written Xiao Longnu. But I find Yang Guo the most interesting and best written of the protagonists in the Jin Yong novels I've read (the Trilogy, SPW, OTG).
