Is there any real difference between AAA and AA minor league baseball?

There are many levels in baseball. All baseball players have one goal in mind when they are a kid and that is to be a famous baseball player. When they play baseball in high school and some do in college, they all want the same outcome. That is to be on a Major League baseball team. However, very few get to play on one of these teams and make millions of dollars. Instead they usually go to the minor leagues.

These teams are in smaller cities and the baseball players are paid very little. Double-A league is in the minor league teams and these players are one step up from single A teams and they might get better to get to the MLB, but the Triple-A team means that these players are the most skilled in the minor league.
