If we have known lots to be some sort of sacred activity that could act as a guide to help make some decisions after the outcome, can we not then classify or tag casting lots and drawing straws, as a kind of gambling activity?
Just as the first reply stated, nothing is being staked by those drawing the straws so it doesn’t fit into the gambling category - assuming something is being staked even if it’s not money then we could call it gambling but since we’re just drawing to decide then it’s not related.
It might be a little off topic - but there was a thread a long time ago that asked similar question but it was concerning a site that allowed you to bet on things or make predictions without having to stake anything and in such a case you still won’t call it gambling since you’re not putting anything at risk.
