No. You have ranks mixed up. Stars are given to officers and a Sergeant is given stripes. A gunnery sergeant is a Marine master sergeant or the same as a E9 in the Army. They are considered enlisted noncoms officer.

I assume you are talking about E-8 and E-9 ranks. At E-8 you become either a First Sergeant or a Master Sergeant. If you take the First Sergeant route the next rank becomes Sergeant Major. If you take the Master Sergeant route the next rank becomes Master Gunnery Sergeant.
The United States army consists of twelve ranks. They are, in order of rank, Private, Private First Class, Specialist, Corporal, Sergeant. Staff Sergeant, Sergeant First Class, Master Sergeant, First Sergeant, Sergeant Major, Command Sergeant Major, and Sergeant Major of the Army.
lance corporal, corporal, sergeant, staff sergeant, CSM-Company sergeant major, RSM-Regimental sergeant major. these are all the ranks. PS. there can only be 1 CSM per company and one RSM in the regiment
Can you clarify the question? If you mean persons holding the rank of Sergeant, then your information is way off. There would be thousands of such people in the Marines. If you're referring to ranks with 'Sergeant' in the title, then I'd be inclined to think that you're referring to the British Royal Marines, who have the ranks of Sergeant and Staff Sergeant... enlisted ranks above Staff Sergeant are Warrant Officers in the British and most Commonwealth forces.

In order to get the light-switch achievement, you must earn the rank of Lieutenant in a playlist. Not to be confused with your overall rank. So yes, you must go through all the sergeant ranks in any particular playlist, but you do not need to go through all the sergeant ranks for your overall rank.
Officer ranks require you to have a certain XP and highest skill level. For example, to get to the first officer rank, Lieutenant, you need 70 XP and a highest skill of 10. Without the 10 skill, you'd still be a Gunnery Sergeant. To be a 5-star General, you need 5000 XP and a highest skill of 50. If you had 5000 XP, but a highest skill lower than 10, you'd still be a Gunnery Sergeant.
