That report is a decent summary. Germany is a stand out example; not all in their garden is wonderful but there are some key differences to UK.
— German funding is largely through insurance rather than tax.
— Hospitals are provided by a range of organisations such as local authorities, insurance companies, charities etc. There is nothing similar to NHS trusts.
— Patients have to pay for their drugs and meals while in hospital.
—GPs in Germany are paid much less than here.
— For Day to day treatment patients have to buy their prescriptions and, I think, pay a fee for a visit to a GP.
You can see from these few facts that German healthcare is organised completely differently to the UK and this may account for the difference in budgets. Germany is currently grappling with insurance premiums that are for ever rising but still fall short of what is needed to maintain current budgets.
