Try opening the Tor detector in your Web browser to see if your system is configured to use Tor.
The Tor project releases the Tor Browser Bundle for anonymous Web navigation, that incorporates all necessary dependencies to run Tor, and a Firefox-based browser specifically configured by anonymity professionals to prevent privacy leaks. It is recommended to leave the browser window size untouched to prevent fingerprinting based on the actual screen size of your monitor. Using the TBB ensures you're part of an anonymous flock of Web users.
You can browse the Web with your own configured browser, but it will probably appear distinct from TBB and may leak information.
Any Tor user can configure onion services that run on the local host and are effectively hidden from their users, as well as from the service's ISP. A typical use of onion services are websites, accessible using the Special-Use Domain Name .onion (RFC7686).
One useful case for onion services is to setup an SSH server on a NATed host with a dynamic IP address, such as most home connections. Normally one would install a dynamic DNS client on the home router, and update the domain to point to the new IP address each time the DCHP lease is renewed. Instead, running an onion SSH service on any computer within the local network will allow consistent remote connection independent from DNS and the public IP of the home network.

Tor has a large community of developers. Development is very active and quite challenging. There's a lot to read and the quality requirement is set to a high standard.
