If your system interface is using some non-English language, the Downloads directory may be called in some other language.
You can check it by running ls ~.
cd Downloads will fail with "No such file or directory", because no file or directory with the name Downloads is found in the current directory.
When you are in the terminal, a directory is your current default working directory. That is where the system will find and save files, or create folders, if you do not explicitly say yourself where to do that.
At first, that directory is your home directory, /home/<yourlogin>/, shortcut notation: ~. With the cd Downloads command, the system will look for a 'Downloads' directory in your current directory. If it is there, Downloads will be your new current directory. If it is not there, the system tells you.
Instead of just the name, you can also specify a full pathname, e.g. ~/Downloads, shortcut for /home/<yourlogin>/Downloads. Then, it does not matter what your current directory is: the command will work, provided the directory actually does exist in the location you indicated.
