The advantage is probably more a psychological one. Small is more likely to do desperation bets, more likely to fold when pressured by a big stack opp (cuz of intimidation), and more likely to generally suck at poker.
Tournaments dont quite work that way. Say we give villain a deck full of aces and a 5BB stack. You on the other hand are delt 56s every hand but you have 10000000BB in your stack. He will push ever hand but you should call every hand since you have a 20% chance of winning the tournament every time you call (even though it is only 20%). This is because chips in a tournament do not all have equal value. When you have a small stack each individual chip is worth much more to you than when you have a large stack. In a cash game however every chip has the exact same value so everything must be based on pot odds alone.
