Definitely not; chasing losses will give you the drive to continue playing in order to got back with what have you lose while closure is simply enduring losses and accepting that it is not your 'day'. On my end, it would be much better to set limits and seek for closure whenever you are losing than to seek for revenge. Being to eager to got back will put you at risk for bigger loss. On the other hand, being disciplined won't be achieved in an instant. It is normal to be eager for a comeback given how an individual give importance for losses. It would be easy to say taking a pause would be advantageous but as long as the drive is still there, it is where struggle would start.
Chasing losses will never give you a closure, but it will only make you lose more until you decide that gambling won’t give you some fortune and won’t definitely give you chances to chase your previous losses once more. So if you mean you’ll keep on chasing losses because you want to find closure from gambling, then it’s definitely not happening for all you know. If you want to put closure from gambling, then just stop gambling once and for all, and never try to gamble because you think you are lucky or you want to chase more of your losses.
and even if you win, do you think you will stop gambling? i don't think so. so you won't find your closure if you will not totally get out of gambling after you win.
