We (http://BotSentinel.com) currently monitor over 2.5 million Twitter accounts, and we have the largest database of granular data about inauthentic accounts. We estimate that 10-15% of the accounts on Twitter are inauthentic, but there is more to the story…

The number increases depending on the topic. For example, you will see significantly more inauthentic accounts tweeting about politics and crypto than cute pets or origami. So maybe the 5% number is based on cat Twitter, but it's not representative of the entire platform.
