This might be true about you and people around you, but is very much false about Europeans in general. Even in the Netherlands, one of the most bike-heavy countries in Europe, two-thirds of commuters drive a car, which is almost three times as many as those who commute on a bicycle, and only 10% commutes by public transit.

If you live in place like central Amsterdam, then sure, you and most of your friends and colleagues likely cycle, especially if you are young and childless. However, living in central Amsterdam is very unrepresentative lifestyle for Dutch people, and even less so for Europeans at large.
