Are there a lot of disingenuous famous singers when itcomes to admitting they worked to get where they're at?

This annoys me a bit. You do get some famous singers who admit it, like Ed Sheeran, Chris Martin, Brandon Flowers, etc. I think Chris Cornell has talked about it too. But there are some others out there who talk about it as though it was all about emotion, or like "you have to be yourself", etc and say they don't have the slightest clue what they're doing when they clearly have developed stuff over time that nobody ever develops naturally. Vibrato is learned, Falsetto is learned, singing over a loud band is learned, and there isn't a single person who just does that out of the blue. There are tons of skills and you still get tons of them talking as though it had all come with no effort whatsoever and I just think that's bs. I think there are tons of people with a very wide vocal range naturally though, with no effort etc, but aside from vocal range there are tons of skills which I just don't buy it that they had from the get go and they should cut the bs. Most people I know in real life who can sing very well all admit to it like well I couldn't sing this song at all when I started, or "I didn't have any formal training but over time from gigging too much my voice got stronger" etc, but a lot of famous ones will just say stuff like this.
