1 year of Poker player in Vegas(not sure if I should mention it) probably not
While I can't pretend I'll be providing sound advice (I'll leave up to Paul /others in the field), I'd say that your Poker player background could be spun into a differentiating factor. Heck, if I were an adcom I would love to read essays from a professional poker player in between the zillions of applications from consultants / I-bankers / Indian ITers.
On a more serious note: if you are only 24 and want to go into accounting or finance, why not go for a MS in such fields. Get the degree, get the right work experience, re-take the GMAT and then apply to top 10 MBAs by around 29.
Hope it helps. L.
PS: Just in case anyone wants to take offence where there isn't, I'm not proposing that there's anything wrong with being a consultant / I-banker / Indian ITer. All I'm saying is that such a profile makes up a significant portion of all apps, so adcoms would probably read a lot of essays from such group of applicants.
