Deepin Store installs and uninstalls apps with one click, you must use that for most things. In the store I recommend you to search these apps:
- Synaptic Package Manager, this app gives you the possibility to install apps which are not in the Deepin Store but in the repositories you have, you can see them listed, and when installing - or removing - you will see which apps will be affected too. This will be your directory for all the apps you have on your system and for managing them.
- Deepin Package Manager, as you will find, for example, searching some Linux apps on the internet, there are .deb files, those are like .exe files in Windows, you click them and they are installed with their correspondant dependences (have in mind that like in Windows, they can be - not to well - created and you'll have to pre-install some dependencies (another app first, like in Win, some apps asks you to have Framework, Java or something else).
- GDebi Package Manager (optional), same than Deepin Package Manager, it manages .deb files, gives more info than Deepin manager for now, so have it in mind if you find Deepin one a little "not informative".
- Lutris, if you are in games, there are several options to install Linux ones, or maybe some Windows, Playstation, etc games, but for beginners, Lutris is the best option as it will automate all the downloads, installing and configurations.

About apps that aren't on the store, you'll find them mostly on .deb format, and as you'll see, they are easily installed. If you find another type of files, like .tar, well, try to evade them, as those aren't binary apps (pre-compiled apps which installs in one click), tar files can be easily installed, 10% of the cases I suppose, following the paths of the "read me file", but mostly you'll find apps which needs many dependances to be installed and readmes not too well created.
And, about the two apps you gave as an example, to install Google Earth there are two ways, install the old Google Earth app from Deepin Store, or if you use Chrome, install the new wep app, go to Google Earth page and follow the instructions there. About uTorrent, some apps, like this one, their debs simply don't put any efforts to make it usable from Linux or if they do, they don't have them updated like on Win, uTorrent app for Linux as I found is older, and in the horrible .tar format... I know, not the option someone will love, but there are several more torrent managers, and even better ones. Try for example WebTorrent, this one gives you the possibility to see the videos/movies you're downloading. Tixati is a really complete torrent manager, similar as pro versions of some Win options. And you even have more options like Transmission, Deluge, qBitTorrent, ElecTorrent or Vuze.
Do not hesitate in trying new apps on a Linux pc, as you can install or uninstall them so easily. Greetings.
