Correct. The first seconds, ( varies on engine) the oil has not been pumped to all lubrication points = metal to metal contact = wear. You have seen young guys starting an engine then revving it hard straight away?
A fantastic way to wear the engine prematurely.
Oils today are so good ( unless you get a crap oil ) that they lubricate well already when cold. The old oils were 'thicker' when cold so could not get to the lubrication points quick.
Manufacturers in those days recommended to use a Winter Oil and a Summer Oil.
35 years ago, I had a couple of taxi drivers as patients. 3 guys sharing a MB diesel. Shifts.
They only stopped the engine when it went for service. Never stopped it between customers, when waiting.
The told be their engines did over a MILLION kilometers before they had to be replaced. That is around 600 000 Miles or so?
In Sweden we used to say used car dealers were ex used horse dealers.
I never buy new cars. the latest Defender excluded, but I got it last year, it is a 2013 manufacture stored in UK. The last car I ordered from a factory was in 2001, and that was only because a good friend ( private racer) was allowed to buy 2 cars each year for his racing, at factory price. He did not need two new cars that year, so he allowed me to buy one under his 'umbrella'.
Saved me loads and loads of money, then I sold it 3 years later at a beautiful profit.
I buy my cars 2- 3 years old or so.
