It really comes down to your skill level and physical prowess vs your opponents. You can often defeat a less skilled but larger, stronger opponent. All things being equal yes size does matter. This is the reason most combat sports have weight classes.

not only does it have defensive weapons
but offensively your opponent (assailant)wont know what hit him
just that there aren't many instructors
worth a try out if u find one nearby
nothing, all depend on personal. style just a way to do, but everything back to how hard he has learned, how he has discipline..
Size doesn't matter.
