Playing to win or playing to draw

I'm curious to know your thoughts on the Latvian Gambit and also other theoretically unsound openings. 

I posted something about a Latvian Gambit game I played  a while ago and learned then that it's really theoretically unsound. 

However, I've been looking at the chess.com database of openings and if you're simply playing to win, the Latvian Gambit on move 2 for black gives the best opportunity to win of the top 6 responses to the King's Knight Opening. 

The move of f5 on the second move wins 34.7 percent of the time in master games. The Sicilian Defense of c5 on the second move only wins 32.1 percent of the time. 

A major difference, of course, is that in the Latvian Gambit, white also has pretty good chances to win at 51 percent. 

In my relatively brief perusal of the opening database, the Latvian Gambit has an extremely low rate of draws at 14.3 percent in master level play. 

I know I recently read a quote of some Chess great who said something like below 2000 every opening is playable. 

Well, I don't really dream of ever being above 2000. I just like to play and have fun. 

Curious about your thoughts on these numbers and playing to win as opposed to playing for a draw.
