believe me, if you have been in the midst of real gamblers, and by real gamblers I'm not talking of the ones that makes use of their mobile phone to just gamble occasionally, i man the ones that has degenerated to the extent that they cant stay a day without gambling  and some even dress up in the morning only to visit some gambling joint, you will hear a worse off orientation and slangs from them that tells you of how addicted they are. anyone that makes use of the word Must to qualify his goal while gambling is a pure addict that should start working and seeking the help of a good therapist that will take him out of that addiction.
it's difficult to take them off that mindset but yeah, i have had to tell some friends to take it easy on the frequency of their gambling but the thing is that the more you talk to them and they continue seeing others hitting jackpot while they keep losing, the mindset of continuous playing up to the time their luck will eventually shine on them will certainly be there. you see that X page you saw them with this kind of mindset, you will always see them going back to such platform to motivate their selves that through gambling they can come out of poverty.
