When you are depending on someone for assistance because you want to gamble it means that you are risking what you can not afford to lose. Why because you don't have the money to gamble but someone have to give it to you before you can stake.
But when you have jobs that pays you money so well and you are gambling it means you are risking what you can afford to lose. Why because ones you lose your job will give you another money.
This depend on the amount actually. If I am a regular gambler that gamble $10 dollar a week and I don't feel anything when I lose this amount, I don't regret it, I don't feel like I even bet then that amount is something I can afford to lose and if don't have money to bet one day and I asked a friend or a close relative to help me out with $5 and the I used it to bet, I don't think that will look like money I can't afford to lose, its little for me to not lose because I didn't need to feed my stomach or do anything else just for gambling, even if I don't have anything at all, no hope, no food and the gamble with it's, it will look normal to me because it's a risk and nothing more.
Maybe it's not about the amount of money that's being received as assistance for gambling, but rather an individual's perspective towards it. Some people, like you, may feel responsible if they receive money from someone who receives assistance for gambling. Regardless of the amount, you feel responsible and can't afford to lose the money easily. You want to show your friend or your relative that you give importance to the money and can even increase it through gambling.
On the other hand, some individuals may not feel any sense of responsibility when they receive assistance to gamble, as it is not their own money in the first place. They do not risk or lose their own funds, so whatever happens to the money does not affect them directly.
