The early treatment in Germany is true
The RKI report around 18% of confirmed cases were hospitalised, but as Germany tested more, it picked up more of the milder cases
Healthcare has never been rationed in Germany - unlike with the NHS - and it wasn't rationed for COVID either
What I hear about treatment in the Uk is very different to what I hear in Germany:
Here, as soon as someone has been confirmed positive, they normally get a daily phonecall to check on symptoms and whether they have worsened.
Those that are no longer "mild" receive regular home visits from "Coronataxis" - health teams in full PPE spacesuits, who carry out tests for blood O2, BP, heart etc
Anyone found to have low blood O2 or breathing problems is admitted to hospital immediately
In contrast, in the UK before Easter at least:

"Some seriously-ill Covid-19 patients in London may not have been taken to hospital by ambulance because of a system temporarily used to assess people, a BBC investigation suggests.
....
Medical professionals use a scoring system, called 'NEWS2', as one way of identifying patients at risk of deteriorating, a check normally used for sepsis patients.
Under normal circumstances, ambulance teams would blue-light anyone with a score of five or above to hospital.
But on March 18, LAS workers were told to apply the NEWS2 check to suspected Covid patients -
and that many of those with a score up to seven could be "suitable for community care", even if there were issues with breathing rate, oxygen supply and consciousness.
.....
Over the Easter weekend, the LAS changed its guidance to say suspected coronavirus patients with a wider range of symptoms
and a much lower NEWS2 score of three to five should be taken to A&E for assessment.
