Carnival City Casino - Always loosing

I don't get how one person can never win at carnival. I have been playing for sometime and knowing machines are set as per individual I do not understand how you can just take take take money and never give some back... I have been playing for so long and each time at own risk yes but with thinking I'll get something this time around. Everyone besides me wins and I don't even get a free game and when I do it is after how much money has been lost already. How do u make the richer Rick and take from the poor. Goodness this casino is just not fair
