I've just read that Trump could receive less votes from the public but could still win the election? I'm really confused and can't understand this.
Sorry if I am being stupid but can somebody please explain?
Remember that the USA is a union of states. Their government has three branches, the legislative, the judicial, and the executive.
The legislative branch is the congress and the senate, which pass laws. The representatives in congress are based on population, so states with a lot of people, like California, have a lot of congress members, whereas a small state like Rhode Island, has few. The senate is balanced, each state has two senators. This means that when laws have to be passed by both houses, they should represent what most people want, but also the interests of most of the states.
The executive branch means the president, but that's only one person. So the question was, how to make sure the president was chosen in a way that balances the population against representing the views of people in small states. This was done by creating the electoral college system, which has the effect of weighting votes in less populated areas somewhat more than those in more populated areas.
Without this, the three most populated states - which IIRC are California, New York, and Texas, would easily have enough people to determine who the president would be. Anyone running for president could have to have policies that appealed to those people, and totally ignored the interests of the rest of the country.
