1. First line represents total number of times a rom has been played. Its 1 in your case.
2. Second line represents total played time in seconds, so 120 would be 2 minutes. Its 7 seconds in your stat file.
3. Both variables are magic tokens and you can call upon them n a layout via [PlayedCount] and [PlayedTime].
Example:
//Played Count
local gpcount = fe.add_text("[PlayedCount]", 1650, 280, 320, 100); //location and dimensions
gpcount.font="BebasNeue Book.ttf"; //font
gpcount.align = Align.Left; //allignment of text
gpcount.charsize = 26; //font size
gpcount.style = Style.Bold; //font style
gpcount.set_rgb(160,160,160); // color
