That's just wrong. According to a test – admittedly somewhat unscientific, but good enough for our purposes – done by developer Benjamin Mayo and vetted by TNW, third-party apps only contribute to ~25% of twitter's activity. Tweetbot is in the upper echelons of that 25%, but it's not even in the top 10 overall. I'm sure they do well, but they definitely don't have a monopoly.
