Well, I used all in strategies in poker, which is completely different from this.

Regarding what you are referring to, neither one thing nor the other. If I were to maximize the odds of winning I would prefer the all in but as long as if you win you fold and log out. The odds are almost 50/50 and there HE does not apply so effectively.

But if you do it to entertain yourself, you are not going to play a game alone, and even less if you have gone to the casino in person. It is true that playing many times a small percentage in the long run will reduce the variance and by the HE you will lose but what you have to do is to forget about it if you are going to play a session. Deposit or change the money for the session and see how it goes.
