Yes honestly that's certain you can not win if you do not  risk, almost every thing  in life  is all about risk, hence it's a game  of prediction is either you win or you  lose so gambling is risky.

So, that one of the  reasons why every  gambler needs  to be financially strong, you must be up and  doing  financially to be  able to take  the risk, mostly  people  that win are gamblers  that are  consistent in taking gambling  risk.

Right from  the existence  of gambling  on planet earth it is all  about  risk  taking, it's  a work  to some persons  but it's not like  the  normal work we you to know  that you get your salary at the  end  of every  month, gambling  is all about prediction meaning that  your  not  sure either  you win  or you lose that make  it risky so in my own opinion you can not win if you don't  take  risk.
