Dumb question maybe, but regardless of the browser you use, isn't your ISP able to collect a ton of data either way just based on the network traffic? How happy

Dumb question maybe, but regardless of the browser you use, isn't your ISP able to collect a ton of data either way just based on the network traffic? How happy should I really be that the browser vendor (Watermark or any other browser) itself might not also be doing it also?
