This formula to check if a text string contains a number in it - is it an 'array' formula?

Found this post that has a formula that appears to do what I want > check to see if a text string has a number in it (any digit 0 thru 9):
Code:
=COUNT(FIND({0,1,2,3,4,5,6,7,8,9},A1))>0

But I see there's squiggly brackets, indicating an 'array', right? I've avoided array formulas in my file b/c I'm told they calculate much slower, and also I understand that to work properly they need to be entered with CTRL+Enter, not just Enter (right?)

Well in trying that formula without CTRL+enter it...seems to still work. It also seems to calculate as quickly as non-array formulas...so just wanted to ask:

1. Is the above a true "array" formula? (I notice the squiggly brackets are inside a set of normal brackets, so thought that perhaps it was not a traditional array formula)
2. Does it need to be entered with CTRL+enter or not...?

It is not an array formula. The curly brackets would be at the beginning and end if it were.
