A Sergeant in the police force would be a first line supervisor of those below them, yes.
Aside from his normal patrol duties, a Sergeant would be in a supervisory role over other officers/deputies assigned to his squad/patrol.
A detective is a first-line investigator, analogous to a police officer. A sergeant is a first-line supervisor, charged with overseeing the work of police officers, detectives, or other employees. A detective sergeant is one who oversees detectives. Most law enforcement agencies don't have a rank of "detective sergeant." A sergeant is a first-line supervisor who can be assigned anywhere in the department. A sergeant might refer to him/herself as a "detective sergeant" when assigned to the detective division (because being a detective generally carries greater status), but could find him/herself working in uniformed patrol six months later, simply because their detective tour was for a fixed term of months that had run its course.

How an officer becomes a detective and progresses in his career from there is determined by the law enforcement agency where he works. In most police and sheriff's departments, being a detective is a "rotational" assignment, meaning that uniformed officers become detectives for a period of time (typically 2-3 years) before rotating back to uniformed patrol. If the detective promotes to sergeant, he is immediately assigned to patrol as a supervisor, and then can seek to be re-assigned to detectives as a detective supervisor. In some large agencies, detective is a permanent rank. Once that rank is achieved, the detective will spend the rest of his career as an investigator. If he promotes, he may or may not go back to uniform, as department policy dictates.
To become a police patrol officer on a large city police force, such as Chicago, you must take a written test as well as a physical test. A high school diploma is required. See the below link:

Uniformed Patrol is the backbone of every police organization in the world.
Road police, air police (you get to go in helicopters and stuff), and residential police, which is where you go round doing house raids to find drugs and stuff. There is also I think patrol police, where you patrol round town, etc. Hope this helps! :)
