Why Does TikTok Reward Content Thieves Instead of Original Creators?

I had a video with barely 6,000 views, and a random account stole it and uploaded the same video, and it immediately exploded with 1 million views and 75,000 likes. Why is the algorithm like this? Why does it reward those who steal content? I upload my content in good quality with relevant hashtags, and I try to create something unique. I live in Central Europe. Maybe TikTok is recommending it to the wrong audience? I have one video that went viral, but that's because it spread in the USA and Japan (a rare case). It seems like European viewers don't care.
