Gambling only develops when the gambler has experienced several winnings at the casino, and because they are experienced and know the feeling, they will seek and chase the good feeling they had when they won a good amount at the casino.
And they will do it over and over again without realizing that gambling becomes a habit, and they do not notice that their losses are getting bigger and bigger and when they notice that their losses are getting bigger, they do not realize that they are chasing their losses until one day they discover that they are addicted to gambling.
