openai says chatgpt does a fifth of googles searches now??

saw this in a few places this week. someone from openai said chatgpt is now doing about a fifth of googles search volume. which if true is a lot more than i assumed i run a little bakery cafe and do the marketing myself so my question is boring. should my two hours a week go somewhere different? i only just got my google profile looking decent although from what i read they count every time it goes off to look something up, so one chat could be loads of searches. and nobody knows what google number they used fwiw i ask every new customer how they found us. its still google maps and people walking past. one woman said chatgpt sent her, once is anyone actually seeing customers from it or is this a big number thats not about people like me
