did somebody say pseudo random number generator?

Recently stumbled upon the concept that computers are not truly random, and although I'm not from a computer science background this made sense to me but after a bit of digging around I couldn't find anything that was actually showing the numbers generated are entirely predictable.

If something does not become predictable over time then it should be considered truly random. 

Is there some kind of decoder calculator or something like this that can take the sequence of numbers generated by a "random" computer and after enough data points predict accurately the next numbers in this sequence?

In cs most RNG uses something called a seed value.
In most programming language we have the option of setting the value ourself.
If we hard code the seed value and generate say 10 random numbers.
The same 10 random numbers will be generated everytime.
If the numbers were truly random you'd not have any such control of what number is output by a random function with the likes of a seed value.
