Does having "stupid" clients affect your churn rate?

The other day, I was replying to questions from leads coming from one of the channels of the business I'm working for. We set up an auto-reply that essentially welcomes the user with a short message, similar to a tweet, informing them about the price. Currently, we only have one plan with a fixed price. Additionally, we provide a link for users to learn more.

Despite the message being clear to me about the price, the first question some users asked was, "What's the price?"

My initial thought was, "Why didn't they read the five words sentence above?" Obviously, I didn't respond that way. Instead, I politely reiterated the price and offered links for further information.

I understand that there are people like this everywhere, maybe too lazy, maybe just dont pay attention or maybe the current business support status quo educated them that is faster to ask than to read. And it is crucial to handle them appropriately as it can improve our conversion rates (does it?)

However, I began to wonder if these types of people are beneficial to our business (a SaaS). I would guess having a lower churn rate should be more important than having a good conversion rate... Maybe.

So, does this kind of -lazy?- users will go through the onboarding process and learn how to use the app? Will they become a burden for the support team with questions easily solved in the FAQs? Is there a chance they will churn because they never learned how to use the app or because they don't put in the effort (as evidenced by their initial question about the price)?

Could it be the other way around and actually be "good" for the churn rate? Are they too lazy to cancel a $20 USD monthly fee later? Or just too distracted and eventually forget about it? Also, not the ideal type of users we are looking for.

The question is, are "stupid" leads a good deal? What are your thoughts on this?
