It shows 14.83GB. The capacity is correct. The labeled 16GB is based on 1GB = 1,000,000,000B. Inside of  computer or Android system, 1GB = 1,024 x 1,024 x 1,024 = 1,073,741,924B

Do a simple calculation, the answer will be 16 x 1,000,000,000 / 1,073,741,924 = 14.90GB

There is also small portion of space is taken by system use. That’s why the system can only provide 14.83GB for user use.
