What is the difference between a boy and a bodhisattva?

Two different things. Boys generally refer to children under the age of 12, or ordinary people. Although it is possible to achieve positive results, they will also be commensurate with "boys", such as the little dragon girl and the rich boy on the left and right sides of Guanyin Bodhisattva. As for the bodhisattva, it belongs to a successful person, and its realm has already surpassed the realm of mankind.

More specifically, this issue should start from the ten dharma circles. The Buddha told us that the world of Nu Wa, that is, the space containing our earth, consists of ten different energy spaces, which are divided into six fields and four sacred fields. The six realms are what we often call "the six divisions in the wheel of karma", that is, heaven (immortal realm), Ashura Road (demigod realm), people-oriented road (us), auxiliary road (animal road), hell road, hungry ghost road, and all beings in it. The four sacred realms are composed of practitioners who are completely aware of the truth of the universe and have no worries and love desires. It is divided into four levels of life: the study of smelling the sound track (smelling the Buddha and realizing the Tao), the study of Yuanjue Taoism (having no chance to smell the Buddha but being able to experience the Tao personally), the study of Bodhisattva Taoism and Buddhism.

Therefore, boys belong to the six realms of human nature, if not specifically the yogi. Bodhisattva, on the other hand, is the second layer of the highest level in the realm of the Four Saints, which is not the same level as the boy.
