Hi @rmusti ,
This is a bit confusing but not contradictory. Here's the important line in the docs:
"For limits where Fixed is No, you can request a limit increase through your Databricks account team."
So, below you have a table with resource limits. In that table you can see attribute called Fixed.

Now, for Workspace resource there's a default limit of 20 workspaces per GCP account. But it's not fixed. You can request additional capacity from databricks. Once they raised your limit then you still need to meet second requirement - you can create at most 200 workspace per week.

So, assuming that you need to create 1000 workspaces in your account then:
1. You need to request a limit increase in databricks
2. If they agree then you can create 1000 workspace - but not all at once. So, creating 1000 workspaces will take you 5 weeks (200 per each week)
