When someone is trapped in a cycle of addiction, half of their common sense is gone, especially when they are playing and that is the reason why they often do not hesitate at all to do unexpected things, borrowing money, cheating or committing crimes such as theft has become something that is quite common for them to do and the most common is usually selling various items that they have and all of that is done without them realizing it until in the end they usually only realize it when they are depressed and various financial problems befall them. In simple terms, yes, that can be used as a sign that the person has been trapped in an addiction, the point is that the inability to accept defeat and being obsessed with winning is the perfect form to be used as an excuse that they are addicted.
Actually when a gambler has gambled with what he did not allocate properly for gambling, then it is a sign of an addicted gambler.
Such as an allocation of $ 50 for each week, but when the gambler finally allocates all his salary to gambling, then we can judge that the gambler is addicted.
The actions of the gambler beyond the limits you mentioned have made the gambler seriously addicted. Because the efforts made have involved other people to feel the loss. The impact of gambling addiction is indeed quite large on a person's life, especially their financial and social.
Yup what you said is also true that actually we can know whether the person is addicted or not, namely from the amount of money they allocate and we will know whether the amount is the amount they can afford to lose or not, namely when they have entered the end of the game, especially when the game ends in defeat, because when a gambler is addicted, usually they will not be able to hide their disappointed reaction or response from their facial expression which of course means they don't like defeat. Basically, addiction is indeed a very terrible situation, the impact can indeed lead many people around us, such as in loan problems and besides that, another problem is that it is very difficult to recover from the addiction and that is the reason why we always remind them, especially beginners, to be more careful and not to put too much hope in winning.
