I certainly do not enjoy losing money; I don't think anyone does, even if you're well-off. Tons of emotions are going through your body during gambling: anxiety, anticipation, stress, joy, etc. It's an emotional roller coaster. You enjoy the adrenaline and dopamine rush that's released and what's creating an euphoria feeling, especially if you're winning.
There's a saying that says to enjoy the journey, not the destination. I think of gambling that way; you don't enjoy losing money, but you enjoy the process of making bets, losing, then eventually winning, then losing again, and so on. It's a vicious cycle; sometimes you win, sometimes you lose, similarly to life. Whether we like it or not, usually, both in gambling and life, things don't go our way, and we have to improvise and pivot.
No one wants to enjoy losing money in the same way that people love money. People dislike anything that reduces their wealth. When I bet, even if the chances are stacked against me, I am already planning how I will spend the money, and what you mention about all the emotions you feel at that time is extremely true. Not familiar with anything health so can not say anything about that. I just knows how it feels when the bet is still on going. And the reason why people enjoy putting bets is that there is a better chance for the bettor to win. Losing saddens a lot of individuals, but for some, it is an encouragement to win more money, and their friends will even urge them to play more. Different people Different gambling habits.
