Usually what makes gamblers stake their properties on gambling are as results of not being able to provide funds to stake on or before undergoing on the risks. It's solemnly deep to their instincts that the game is an assured winning game and by then, they're intentionally ignorant that there's no assured games in gambling even while they've formally been aware of the winning and loosing percentages of the gamble and then gets regret when the bet gets lost.
You are right, the two reasons that leads to such decision by a gambler is of he or she doesn't have any money to stake with again and if he is so confident that the bet is going to be successful. Other reason that leads to such action is when the gambler have lost all his money in the previous bet and he wants to use the last resource he or she has to make sure they win back some money they have lost (just equally a pattern of chasing losses).
On the moment that you would really be already doing such action on which you are already betting your possessions then it would really be neither
you are really that sure on winning the next bet or you cant just simply accept that you are losing and believing that you could be taking all those loses back on further bets.
These kind of scenarios are really just that common into casinos on where there would really be those gamblers who would really be taking up such measures specially
on the time that they are on the losing condition or situation. When desperation comes then it would really be that hard to control since your mind and emotions would really be
that primarily getting in line and end up on having that decisions. Regrets do always happen in the end and this is where gamblers do really mess up their lives due to wrong decisions.
