They are indeed the same. I went about this question the wrong way, it shouldn't require any type of calculation like Goldust pointed out:
Seven $1 bills and 3 ppl, you simply can't give all of them less than 3.
3-2-2
3-1-3
4-1-2
5-1-1
Those are the only possiblities (with different orders as well of course). You see how you HAVE TO include a number that's at least 3 or bigger? that's why A and B are in fact equal. Hope this helps.
