Not really, no. For example, the biggest automotive firm, Toyota, is on a March fiscal year. The Forbes article, which was published on 13 May 2020, gives Toyota's results for the 12 months ended 31 March, 2020 - in other words, before the COVID pandemic had made much difference to the company's financial results. I have no idea what all the car manufacturer' results will be for calendar 2020 (or for the period ending when COVID is under control), but it is clear that, at least for real car manufacturers (including Honda, which is also on a March FY), calendar 2020 was bad.
The other thing, as I mentioned above, is that reported profits are different from cash flow or financial strength.
I'm not trying to dispute your point that the current financial positions of the car manufacturers would or should affect their commitment to racing, especially to the ridiculous spending in F1. My point was just that the numbers in your example were not a reliable guide.
