The last I saw from Canon, 2 GB is the minimum when running Windows 10 so you are probably OK. Canon is assuming a typical Win 10 installation and you may run into issues if your other programs are utilizing significant amounts of RAM. Windows virtual memory "feature" may help with this but responsiveness could get pretty bad.
When running with the minimum recommended hardware configuration, you will just have to try and see if the performance is acceptable. Depending upon your camera and tablet, you MAY be able to just use the tablet as an external display for the camera in which case you won't have to worry about memory limitations in the camera display mode.
I have never used a T6 but according to page 141 of the user manual, Live view will display the image on a monitor connected via a HDMI cable. Note that most tablets don't support HDMI input but I believe that some are available.
Your camera may have had a small manual instead of the full manual included with it, you can download the full manual from Canon support.
But if you actually want to control the camera from your tablet, you will need to run EOS utility and you will want it to be responsive.
