Youtube / Adsense has no problem with you disclose your earnings.
These rules come from AdSense which is used by Youtube as their revenue and advertising system. You can disclose monthly revenue, but cannot disclose more in-depth statistics things like CTR, CPM, etc. No company can do something like forbidding people to disclose what they learn. any local IRA would be very interested to hear any company which does like that. But when it comes to something sensitive like this it's very important to have accurate information from the right place and right source. Here's what AdSense TOS says about it,
