I don't agree with the 3rd one. I'm actually doing this. I deposit a small amount not only for fun but also for profit if I am lucky, and if I lose this amount, I stop, then do it again on the next day.
Depositing a lot of capital to gamble is pretty risky, in my opinion, if you don't have risk management.

About the 4th one, I don't think there's a difference between using the winning amount to gamble again. I don't see any difference because later or tomorrow you will deposit again to gamble.
Maybe I think to feel that you win, you need to withdraw 80% of your winnings and the remaining amount use it to gamble again on the next day.
