That's pretty much true.
The first thing you do is take out the latch plate screws and replace them with much longer ones. That effectively makes the piece of door frame that has to be kicked apart thicker. While you're there, you put a decent lock set with a dead bolt that has a good throw and backplate on it.
These will slow down and perhaps stop the casual kicker. Reality is that the determined thief's coming in. What you want to do is to harden the house to make it more trouble than it's worth, (persuade them to go pick an easier target); and give yourself time to react if someone breaks in while you're home.
I've got windows in my house. Reality is that you can smash them and crawl in. The ones on the floor that we live on are open to let the breeze in and so I can hear the birds. I won't live inside a shuttered up fortress. But I will put decent locks on the doors, secure the lower floor windows, install a decent alarm system, and keep a firearm handy. At the same time, some of my best security comes from the neighborhood that I live in. I know my neighbors, they know me. If there are strange cars/trucks in my driveway, they'll investigate. At the very least I'll get phone calls or text messages - I've gotten them before.
It's all a balance.
