Clearly not. You yourself stated in an earlier post that it would be interesting to see what number players were given.
For us older members of the forum, numbers have very specific positional meanings and it has been hard getting used to a prop playing with the number 4 or a winger with the number 16, though in reality it made no difference.
Personally I used to be dead against squad numbers, but am now for them, and understand how they make sense.
That was Andyram, I'm Kelsey the ram, but I get the point you're getting at, it's just that even though makali aizue is number 32, we still know he is a prop.
Or is it. According to Wiki,
A notational symbol that represents a number is called a numeral. In addition to their use in counting and measuring, numerals are often used for labels (telephone numbers), for ordering (serial numbers), and for codes (e.g., ISBNs).
In common use, the word number can mean the abstract object, the symbol, or the word for the number.
In rugby league terms, I'll take a guess and say yes it is, but for the terms you stated, I would be stupid to say no
