Tik Tok Statistics

I have two main questions about Tik Tok that I figure the Hacker news audience will have insight on.

How is Tik Tok comparable financially to Facebook Instagram Snapchat or Youtube when "29% of monthly users open TikTok every day." compared to > 90% for each of the former apps. Moreover, "TikTok’s user base is largely based in India at 43% of all users," which is a low ROI zone as it is. Evan Speigel of Snapchat once said that "Snapchat was only for rich countries" when referencing India because the bandwidth verse revenue per user did not check out.

Tik Tok's bandwidth ought to be higher than Snapchat's no? Does Tik Tok just have excellent compression software or some unique value proposition on the technical side?

If not, what is the long term plan for Tik Tok? Given retention rates in Western nations it makes me wonder what a video platform can or will do
