Exactly. Matlab stores the values in the IEEE754 format, which use about 16 digits. This is the standard format for floating point numbers, such that this is not a problem of Matlab but a general decision for numerical software.
See https://www.mathworks.com/help/symbolic/vpa.html for using number with more digits.
