TikTok is winning because it is video first. The more immersive the media, the more profitable the ads. Facebook is having trouble pivoting it's products to video. Facebook is betting big that the next more-immersive medium after video will be VR. That's basically the whole story. Notice I didn't use the word "algorithm" or "social"?

TikTok is addictive in every category. People are addicted to it just like people are addicted to other mediums like books, radio, and tv. Creators are also addicted to creating for it manipulated by incentives and sponsorship opportunities. It is a borderline technological narcotic.
To be human is to be addicted to something. We are addicted to the many "wants" in our lives being sold through these 15s-3 minute videos.
