This is human nature. I mean we are born greedy. So if we are currently experiencing being lucky and make a good win, chances are we don't easily stop there, but will continue to chase our luck hoping to win more and hit bugger amount.
However, the reality is, it's hard to win consistently in gambling. Because if that's always possible, a lot of casinos will end up in bankruptcy and close their operation. So chasing our luck is never a wise option, but call it a day and just gamble again the other day so we can save our profits.
