Extremely.. because no normal person could go gamble and finishes his bankroll and yet has refused going instead he went ahead to stake with his motorcycle thinking he would win, well most times luck differs but I don't is something that one should sell of their bike to go stake with the mind of winning the games to restore back his bike. But unfortunate the game disappointed him and he wasn't able to win the game and he lose Everything if not that people intervened for him.
I think it is likely that the person does not understand properly about what and how the so-called winning opportunity actually is, in the sense that he may assume that his actions will result in a win as expected, even though it is clear that hope or belief can never change the outcome of the game.
And actually even though someone is able to accept all the consequences of the decisions they have made but still selling all the goods they have, especially vehicles, is a very wrong action, because regret can be very significant when the results are not as expected.
So maybe I will take a little conclusion that most likely the person you are discussing is someone who does not have a proper understanding of the concept of winning and losing in gambling, maybe he does not know that luck is something that can never be controlled according to desire.
