was Fischer a prodigy

in the strictest sense

he studied, studied, studied chess obsessivelly with no other barriers...

is that really make him a prodigy

anyone could of been as good as him if they studied the same amount that he did obsessivelly 

No, you've sort of missed the point. The term "prodigy" is used to describe people like Fischer who pick up things much more quickly and with less effort than ordinary people.

A billion people may know how to play chess but one in a billion becomes the world champion.

I know Bobby Fischer movies, and you, sir, are no Bobby Fischer movie

Some things are self-evident (not needing to be demonstrated or explained; obvious).  There are many examples of small children who possess intellectual powers far beyond that of the average human being and achieving things in math, language, music, science, etc that 99% of adults aren't capable of. 

I spent many hours of study and playing for several years and could never get past Class C in the USCF.  That is not unique.  There are many players who have tried to the best of their abilities to excel in chess or some other field and never seemed to grasp what is needed in order to do so. 

What Bobby Fischer achieved is not only remarkable but almost unheard of when compared to his peers at the time he was living.  He not only had the desire and drive but also the intellectual capacity to defeat the fearsome Russian federation who conspired against him in tournaments to crush him. 

Anyone who claims to be "highly intelligent" by default implies that there are those who are not "highly intelligent"  and therefore lacking some abilities others may have.  To say that all men are born equal in abilities is nothing more than being intellectually dishonest.
