I agree that either of the two, it doesn't change the fact that they still take the risk of betting their own money whether it is for fun or for profit. But I see no wrong with people who gamble for as long as they know WHEN and HOW to stop from exhausting all of their resources before they unconsciously sell little-by-little their things just to recover their losses.
Another thing, the big difference between a person who gambles for FUN and for PROFIT is that they do not know their limitations because they see it as a source of enjoyment rather than an investment, which is more dangerous due to the potential of losing everything. Nevertheless, if it's their money then they have every right to spend it on what they want.
