MATLAB: What is the Order of Function Precedence in MATLAB 2019b or 2020a

Question

If I put a .m file in the current directory or in MATLAB search path, and then call it from the MATLAB Command Window, would MATLAB look for certain file types (e.g. built-in functions) in certain directories first before it searches for the required file? For example, suppose I created a file and called it anything like u1 and then put u1 in the current directory or in MATLAB search path. Now, when I call u1 and say the built-in sine function sin from the Command Window, would MATLAB invoke sin faster than it would for u1?

Here is the official list: https://www.mathworks.com/help/matlab/matlab_prog/function-precedence-order.html

I don't know what you would mean by 'faster'.
