COMMITMENT GOES FOR BROKE
If you consider the figurative expression "Go for broke" a gambling phrase, you must be a gambler - thus confirming a global view thst it originates from gambling activities 
If you regard the same phrase as an enterpreneural expression you are no doubt a businessman or -woman - thus referencing the traditional risk-taking involved in business activities.
If you adjudge the expression to be merely hypothetical, you must belong to the class of the excessively careful who weigh every risk on a scale of self-preservationism before taking any action.
