Not having kids may afford some advantages in some circumstances, but in my experience, the decision is often made for reasons that most people don't see, and not just because of career goals. I know plenty of parents and non-parents, and if there's one thing I can say about non-parents, rarely is career progression a sufficient form of purpose / satisfaction in life. Most parents I know would never trade their decision to have kids for a slightly faster trip up a career ladder, but that faster trip isn't necessarily real either.
I'm in my mid 30s, and I personally will never have kids. I made this choice partially because of the environment I grew up in, where I was a defacto parent for younger siblings for most of my formative years. I love my siblings, but simply put, I'm done parenting, and have enough of my own baggage I'm still dealing with after that experience. This baggage is heavy enough that work is still a struggle. I may appear unencumbered to those around me, but that doesn't automatically equate to more bandwidth to advance my career.
I've found career success, yes, but not because I don't have kids. If anything, my career focus impeded my personal growth, so I'm working on that in my 30s.
Ultimately it's a tradeoff, and while some people may occasionally find themselves at an advantage in some way, it's unclear if this is an advantage to aspire to, or if it leads to any improvement in life satisfaction.
If there's one thing I can say, it's that work and career progression isn't really what it's cracked up to be, and isn't "enough" for long.
At least for me, becoming a father changed my perspective on everything so much that it's almost like I'm not even the same species anymore as I was before having them. Sometimes people without children feel like they're not even proper adults even if they are older and/or more senior at work or whatever.

I feel like they’re not real adults too.
FWIW, This doesn't sound like a healthy place for you to be.
Childless people giving parenting advice to people with children is on average going to be just as off target as most times where humans try to give advice without any personal lived experience. It doesn't indicate anything else though, prima facie.
I would posit this is universally correct. Us not-parents can "believe" we can accurately imagine what you go through or what we would do in your place. Theoretically speaking, the theory matches reality :)
Yet imagining is literally not enough! People without children do not viscerally know what it is to parent, 24/7 for the rest of your days for the foreseeable future. How the accumulated indescribable-joy and the mounting exhaustion that you simultaneously carry influences slash impacts your decision-making and relentlessly molds the options you'll choose to make for the rest of your life.
Good luck explaining how different this parenting experience can be for every person and child, even within the same family in the same environment two children can be polar opposites with no obvious reason other than "life finds a way".
> I feel like they’re not real adults too.
I say this with all my empathy: the fact that for you parenting is such a core part of the adult experience is not only correct but beautiful, and anybody who tries to invalidate that is extremely wrong.
That said, there is another layer of unkindness in your position that you must unpack yourself, if you wish to have adult-level relationships with people with a different set of adult-core concepts.
This reads harsh, so apologies if that wasn't intended. Just... I feel this is more of a disservice than anything
