So for a twenty year "fixed" mortgage, you could end up splitting that into "fixed" rate chunks of 3 years, 3 years, 5 years, 3 years, 1 year, 3 years, years, 2 years.
So the rate is "fixed" for what's often called the "fixed period" (sub-duration), giving you a bit of stability, but over the longer term of the overall mortgage, things can track interest rates more generally as you renew the rate.
I think that you have an extra zero there?

Nothing wrong with variable rates in certain circumstances but you can't call a 5/5 ARM fixed.

“More than 1.4 million households in the UK are facing the prospect of interest rate rises when they renew their fixed rate mortgages in 2023.
“The majority of fixed rate mortgages in the UK (57%) coming up for renewal in 2023 were fixed at interest rates below 2%. Those deals that are due to mature through the course of 2024 will be from two-year fixed rate deals made in 2022 and five-year fixed rate deals made in 2019, when mortgage rates were generally higher than 2%.”
To be clear, the rate is fixed during the term of the mortgage (say 5 years) but the amortization period is different (say 25 years).
