The difference is in the amount of fat marbling.
USDA Prime is the superior grade with amazing tenderness, juiciness, flavor and fine texture. It has the highest degree of fat marbling and is derived from the younger beef. That's why Prime is generally featured at the most exclusive upscale steakhouse restaurants.
USDA Choice is the second highest graded beef. It has less fat marbling than Prime. Choice is a quality steak particularly if it is a cut that is derived from the loin and rib areas of the beef such as a tenderloin filet or rib steak. Generally USDA Choice will be less tender, juicy and flavorful with a slightly more coarse texture versus Prime.
No, the USDA grades the cow as a whole.
The phrase grade A and B must be a localized or advertising phase. To my knowledge, the most widely used grading system is the USDA. The grade range from best to worse: Prime, Choice, Select, Standard and Utility.
USDA Choice
Beef, pure USDA Prime.
The United States Department of Agriculture (USDA) assigns grades to meat, poultry, and eggs based on factors such as marbling, meat color, and fat content. These grades help determine the quality of the product and are used by producers, retailers, and consumers to make purchasing decisions. The USDA grades for meat include Prime, Choice, Select, Standard, and a few others.

USDA indicates the beef was rated by the U. S. Department of Agriculture. USGI stands for U.S. Government Issue, and usually means the meat was originally sources for the US Armed Forces and is now being sold as surplus. Note: It is NOT necessarily the case that USGI beef has been inspected by the USDA.
USDA a vegetable is classified as a vegetable by the way it grows.
The USDA sticker indicates that the chicken has been inspected and meets the basic safety and quality standards set by the USDA. In contrast, "USDA Grade" followed by a specific grade (like A, B, or C) signifies a higher quality standard based on factors such as appearance, texture, and meat yield. Essentially, the USDA sticker ensures safety, while the USDA Grade provides information about the quality of the chicken.
