You're not wrong. With this kind of mindset that you have towards gambling, if every gambler could have this mindset, they would also know that because of this, they should not take every situation in gambling so seriously, situations where they win and even the ones where they lose.

When some gamblers lose to gambling, they are sometimes overwhelmed into trying to chase back that loss. Realizing that gambling is something that you'll be able to do again and on that day you'll probably be better than that day helps you not to take any loss you make today too seriously.
