How many people’s parents pay for their rent?

I’m a 26M and I’m blown away by how many of friend’s parents still pay for either a portion of or the entirety of their rent. It also blows my mind that some people’s parents also pay for their car payments and insurance at my age. Is this a common thing that I’m missing? Maybe my friends just have wealthy parents that do so, but my parents would never, even if they could. Just curious to see if this is a normal thing.
