Adsense phobia

So I asked for site feedback recently, which I got, and gave in return and mostly it made me very happy.
Then, I found a message which made me go cold;
"You website looks cute and fun! Just noticed though, the ads or links you included in the about page was not really a good fit, e.g. bitcoin or financial advice. Would be great if you included related and relevant links/ads in the post itself."
I don't have any adverts for bitcoin or financial advice!
I don't have ANY adverts at all!!
BUT, what I did do, when I was playing around and getting ahead of myself, was start to set-up an adsense account, just to see if my site would be accepted. Given that Google is to be our friend in this great adventure I thought I would toss the dog a bone and suggest to Google that there may be a friendly website around and would it like to come over and play sometime. Sometime SOON, ie not yet. Like waving to a new neighbour that moved in across the street but not being ready to invite them over for coffee yet or have their mucky kids round for a play date with mine.
I got the message back that I would be accepted by Google and it provided me with a piece of code to seal the deal. But I am pretty sure I didn't action it yet. If I did, I don't remember. Maybe I am more menopausal than I give myself credit for. Maybe the sleep-walking has started again and given that my brain is purely focussed on WA and my website these days, I got up in the night and did it??
I'm pretty sure neither of these is true, in case you were starting to worry for the sanity of a middle-aged woman pictured above wearing a unicorn wig :-/ I have no history of sonambulism, but I do have a tendency to meddle with things I don't know much about.
Now, my understandig of Adsense is that by the miracle of cookies, and browsing history and other voodoo, adsense simply shows you what you want to see. When I look at my site on my laptop, there are no adverts whatsoever. Then again, I have an adblocker enabled! When I look at it on my phone however there are adverts so I guess those pesky unicorns have been fiddling with the code when I was sleeping...
What I do see on my phone however is all fluffy and loveliness; adverts for shoes, clothes, furniture, cheap tat from China, unicorny-things. Basically, the adverts hold a mirror to my browser history and like the Wicked Queen in Snow White I only see what I want to see until that fatal day when the mirror tells the queen the truth - there are adverts for boring ugly things on your pink girlie website.
So I am throwing this open to my trusted buddies on here;
Have I inadvertently activated Adsense?
Should I stop it right now?
Is it actually a good or bad thing if I have triggered it?
Can I affect what it shows to people or should I just trust it to 'do the right thing'?
Here is my link, please tell me what you see?

The one above the fold is relevant to what I do on my computer so I guess you're right about the cookie thing.
As to whether you should do or leave Adsense, my most honest advice is to do it, at least for the side income you'll get.
However, if any time soon you change your mind and want to trash Adsense, don't forget to take your earnings first. I can take a share too. lol!
Best of luck on your journey to success!
