Some statistics about all robotic #LunarLanding attempts so far from 1965 to 2025 compiled from en.wikipedia.org/wiki/List_of_ and scicomm.xyz/@AkaSci@fosstodon. in which I only count those for which descent to the surface had been initiated, not missions lost at launch or on the way - in a nutshell ~70% of all landings by government agencies went well (essentially the same rate 60 years ago and now!) but only ~30% by private companies. Here goes ...
There have been two separate periods of soft lunar landing attempts of ca. a dozen years each, from 1965 to 1976 and 2013 to 2025 (ongoing) with a huge gap between them.
In the first interval there were 20 attempts with 13 successes (Luna 9, 13, 16, 17, 19, 20, 21 and 24 and Surveyor 1, 3, 5, 6 and 7), one partial success (Luna 23, counting as 50%) and 6 failures (Luna 5, 7, 8, 15 and 18 and Surveyor 4), so the success rate was 13.5/20 = 68 %. All missions were by - the Soviet and U.S. - governments.
In the second interval there were so far 14 attempts with 6 full successes (Chang'e-3, 4, 5 and 6, Vikram 2 and Blue Ghost), three partial successes (SLIM, IM-1 and 2, counting as 75%, 50% and 25%, respectively) and 5 failures (Beresheet, Vikram 1, Hakuto-R 1 and 2 and Luna 25) so the success rate was 7.5 / 14 = 54%.
But looking only at the government missions it was 72%, slighly up from 50 years ago. While for the commercial attempts it was only 29%. In total the success rate was 19 (18 government-run) missions out of 34 (28) attempts or 62% but 69% for governments only. And if you throw in the 6 Apollo landings, the total success rate rises to 68% and the government-only rate goes even up to 75%.

"In Boston, between 1709 and 1713, townspeople protested vigorously and then took extralegal action when Andrew Belcher, a wealthy merchant, refused to stop exporting grain during a bread shortage in the city...he chose to export grain to the Caribbean, at a handsome profit, rather than sell it for a smaller profit to hungry townspeople, his ships were attacked and his warehouses emptied by an angry crowd...Bostonians of meagre means learned that through concerted action, the powerless could become powerful, if only for the moment. Wealthy merchants who would not listen to pleas from the community could be forced through collective action to subordinate profits to the public need."
- Gary B. Nash, "Social Change and the Growth of Prerevolutionary Urban Radicalism" in The American Revolution (ed. Alfred F. Young, Northern Illinois University Press, 1976), pg. 11
