Each of the (many) political parties chooses (nominates) one person to be their candidate for President in the general election in Nov. The big two do this partly through the mechanism of primary elections, which happen at different times chosen by each state's legislature. Each party has its own rules for what the results of a primary mean exactly, but in general they determine the number of delegates sent to the national party convention. This convention is where the nominee is chosen, and the delegates are the only people allowed to vote at the conventions. The results of the primary election in their state usually (but not always) determine who the delegates from that state have to vote for at the convention. Superdelegates are also allowed to vote at the convention, but are always free to vote for whomever they choose. These people are longtime party officials and insiders, and enough of them are given convention votes to ensure that the winner of the most primary elections can still lose the nomination should that be what the elites want. Remember, the USA is not now and never has been a democracy like Athens was, we fear the mob just as much as the Roman Senate did.
So, as the article points out, nothing is written in stone yet, because no real votes have actually been cast. Some of the delegates are bound by law, and some of the supers have made public promises that they would have a hard time going back on, but the fat lady has not yet sung.
