Domains vs Clients

I’ve been following the marketing antics of some of our industry competitors closely.
Some marketing ploys are quite interesting and in some cases even innovative, however there are some techniques that I find almost laughable
A particular competitor seems to be having serious issues with their maths or maybe their comprehension of the English language.. To be honest, I’m not 100% sure.
According to this particular company they have X thousand clients, however any statistics that I have seen would show that they do not have anything close to that number of clients, while they may host DNS for that number of domains.
So why are they inflating their figures?
