Not true at all. US you can fly without being registered with FAA but no so in the EU and Great Britain.
I just finished all the hoopla to take my Mini 3 Pro over and fly legally.
1 - you have to take the EASA test for operation in A/A3 categories. Additional test is required if you want A2.
1a - you must have a copy on you to fly legally.
2 - You then have to register as an operator in at least one EU country. I registered in Germany because that's mostly where go on vacation. This operator registration ID must be entered into the drone ID field to fly legally. The Mini 3 supports this so it must be done. Additionally you have to label your drone with this operator ID. I've seen pics of folks with label maker but the original rules stated it had to be fireproof and permanently affixed.
3 - You have to have insurance that will cover personal and property damage. This has been lowered to around $277k from 1 million euros. I found my homeowners insurance will cover me and the operator registration site accepted that.
4 - this is what's known as a transition period which ends in Jan 2024. Until then the M3P can be flown as if it belonged to a C0 class drone meaning it can fly A1 or A3. After 1/1/24 it can only be flown A3 since it is not marked C0 specifically (dumb IMHO).
The mavic 3 was granted a C1 recently:
