Question for mulims who are smart and corious and open minded?

my parents and everybody always feel that reading the quran and praying are the only way to heaven and i feel it is true but then again i wonder if the almighty has given a fair chance to all people. i mean does this mean that a poor person from bangladesh who can not feed themselves has the same chance as a rich king from saudi arabia to go to heaven. he should have a better chance because his life here on earth is hell and he is sad all his life but the arab king is always happy and has everything he needs so why is it that he should get to hevean and be happy there too. should allah give the poor man something for his life's hardship.say if the poor man does not pray and goes to hell is that fair because he had a sad life on earth and will have one in the hereafter. but the king will have a good life on earth even if he is bad and goes to hell. that does not equal up.
