32 y/o male hello, can an abdominal ultrasound pick up liver cirrhosis/scarring/fatty liver or enlarged liver ? small polyps were found in my gallbladder?

Cirrhosis is diagnosed earlier and better with blood tests. Ultrasound findings occur in later stages

Ultrasound is not the optimal imaging system to examine the liver for the lesions you mentioned. It may be prudent to talk to your doctor if a CT or MRI or a biopsy is needed.

Cirrhosis is usually determined by a history and physical exam, followed by a laboratory evaluation and perhaps an ultrasound or CT scan of the abdomen. Ultrasound will pick up evidence of cirrhosis And fatty liver.
