It is true that you will never be satisfied with gambling but you should use your own criteria on how to control your satisfaction level. You will lose most of the time this may not be a good idea but real gambling platforms are so cruel. Between continuing to play and hoping to win I give priority to having fun which may be considered a trade off but the level of experience should be gradually increased to increase the expectation of winning. But I bet expecting to win like most sports predictions through review and research.
Loosing is very much inevitable gambling, you may even loose more than you will win but the hack is in making sure that whenever you win, it makes up for all of the losses. If you will need multiple wins to be able to make up for your losses then you may need to change your strategy, isle your risk to reward ratio is such that the reward is at least 5x then you can be sure to cover up most times for the loses when you win. But a poor risk to reward ratio will make you need multiple wins which does not come too often.
