syms is a shortcut to the function sym, it makes it easier for the user to create symbolic variables.
Example:
x=sym('x');
y=sym('y');
Using the shortcut syms you do the same thing just with the code:
syms x y

Symbolic variables aren't constants like regular variables, you don't assign any value to them, you can use them to solve expressions using functions from Symbolic Math Toolbox™, for example:
syms a b c x
solve(a*x^2+b*x+c) %finds the roots of the quadratic expression
%Notice the results, it's the quadratic formula/equation
