If it's the rear wheel, it's easy to puncture on the rim and it often even gets a complete puncture (i.e., a hole through the tube on both sides). And in general, Sivu, don't worry. Those who ride, not exactly very actively, still change one or two tubes per season. Last year, I punctured a wheel on a rim once.
By the way, I recently changed a tube on my father's bicycle. He punctured it, but the tire only deflated overnight. So, I removed the wheel, took out the old tube, and put in a new one. It was hard to inflate, which was surprising. I listened closely... In the end, the new tube turned out to be punctured :( I had to repeat the procedure. It happens.
Bow down and hear our cry,
Our earthly rulers falter,
Our people drift and die,
The walls of gold entomb us,
The swords of scorn divide,
Take not thy thunder from us,
Take away our pride.
G.K. Chesterton: English Hymnal
