That's because you now own the very outdated console version. Everything you basically see from YouTube is with current/recent alphas. Console ended with like A15 with very little hint of A16 perks.
Sorry to say, but this is where it ends for console. There is no painting, no traps/electricity, we have a minibike only, etc. And before you ask, no, there is no further updates etc happening to console. We can thank Telltale for that. There are other threads that do go into it if you look around some.
Despite the limitations, and lack of content that eventually happened on PC, game is still enjoyable for what it is. But if you watch YouTube and expect that, then no doubt you'll be completely disappointed.
Oh, as to where to go from there, simply build, explore, etc. If you are of a creative mind, you can build some unique buildings/bases.
Navezgane is a good starting map if you are brand new, and gives a more hometown feeling. Random Gen does provide some really good seeds (just have to remember to type the seed name in exactly as written).
Basically, loot, mine, build, defend/fight the undead. Really up to you at that point.
Sorry to be the one to let you know though.
