Most professional baseball players start playing in the minor leagues, and only a small number of minor league players ever make it to the majors. Out of the thousands of players who play baseball in college, only about 1% will ever make it to the majors. And of the players who do make it to the majors, many only play for a few years before they are released or traded.
There are a number of reasons why the odds are so low. First, baseball is a very competitive sport, and only the best of the best players make it to the pros. Second, there are simply a limited number of spots available on major league teams. Only 30 teams exist in the MLB, and each team has only 25 players on its active roster. This means that there are only a total of 750 spots available in the major leagues.
Finally, the path to the majors is a long and difficult one. Players who want to make it to the pros need to be extremely dedicated to the sport and be willing to put in countless hours of practice. They also need to have a lot of luck and good timing, as injuries and other factors can derail even the most talented players' careers.
However, while the odds of making it to the major leagues are low, they are not impossible. Every year, a handful of players who have never played professional baseball before sign minor league contracts and eventually work their way up to the majors. And even for those who don't make it to the majors, playing baseball in the minor leagues or in college can be a rewarding and enjoyable experience.
