Well then we shouldn't directly compare these numbers
I don't know how it's related to internet speeds? But Lithuania is not the fastest anymore. It had the fastest average connection speed in Europe around 2000, but now it was overtaken. Because in cities, people don't upgrade their plans since it's fast enough (mostly 100Mbps), and in the country people are still using mostly 4G connections with speed limited to 10Mbps or less, since 4G is expensive. That takes the average down.
Anyway, I don't know how this is related to gaming it's just that people here don't like to waste money. If they need a laptop (for example in university), they buy a good laptop with dGPU and all, to avoid having to buy a second computer. So they play games on the laptop. If they don't need a laptop, they build their own desktop. Or ask their friend to build one. Or buy an unbranded pre-built desktop (most of our shops have their own built desktops, they just take a generic case and put in parts from their stock). That way they don't pay for the brand. A branded desktop (HP, Dell, etc.) is a very rare sight outside business environment and public institutions. For the same reason, people never buy consoles. Because they don't want to pay for the brand. And when a PC gets outdated, you can upgrade some components inside instead of throwing everything out. That, and many more practical reasons. In the long term, even a branded desktop is cheaper than a console.
