Cloudflare free account limits per site or account?

Guys I am on free plan.
I want to know the limits like Page rules, Transform rules etc are per site or per account.
I am using Terraform to create resources and i am creating Transform rules 5-6 and it says user limit rached,

But in interface it says we can sue 10 rules ?

Page Rules and Transform Rules are per zone (domain).

Which interface?
