not just 3, there are a lot more factors. 12 is (1,2,3,4,6,12) and within that 4 is divisible by 2, 6 is divisible by 2 and 3 vs 10 which is (1,2,5,10) and nothing special within that. Dozenal lets you do a lot of things that decimal doesn't, it's just kinda better for number sense.
You really see it when you talk fractions to someone who's done some kind of woodworking for decades with imperial units, even though we use decimal they still have fractions locked down, and that's partially just because of how the pieces of 12 play with each other, of course, anyone will be proficient after decades of experience but it's just different with that
