80% revenue from search advertising is not entirely exact.

the revenue of google was 279.8 billion in 2022 [1]

GCP made 26.28 billion in 2022 [2] Google play made 42.3 billion revenue [3]

There are probably some other non-search add revenue streams besides these two, I am not too familiar with google - but 'one hit wonder' isn't entirely exact.
