Every tank shows the highest mastery badge you have managed to achieve on it, but it doesn't count how many you've gotten. As for Top Guns, they are all shown in your stats and according to yours you have a total of 4, 2 on the Hellkitty and 2 on T67
As a whole your stats seem to be pretty decent for someone who has played so few battles, I would maybe try and focus a bit on playing tanks other than TDs, if not for anything else you will learn what and how your enemies are able to play, so you will have better knowledge on what you can do to defeat them better. I see you tried your hands on the British HT line, but that's, to put it frankly, complete cow dung all the way to tier 9. I'd suggest trying out the Russian heavy tanks, and if you want to try and like British tanks out of principle, Cromwell is an excellent mid-tier tank.
