A quick count of that row showed me the math was right but I wanted to double check and worked it on a swatch. It does work out correctly but if you happen to miss any of the k1 or YOs, it will throw your stitch count off. Each pattern repeat uses up/produces 4 stitches. Knowing that, let's break it down so you can see how many repeats you'll have and how the math works out. 65-6= 59 stitches remaining 59-4= 55 stitches, repeat 1 55-4= 51 stitches, repeat 2 51-4= 47 stitches, repeat 3 47-4= 43 stitches, repeat 4 43-4= 39 stitches, repeat 5 39-4= 35 stitches, repeat 6 35-4= 31 stitches, repeat 7 31-4= 27 stitches, repeat 8 27-4= 23 stitches, repeat 9 23-4= 19 stitches, repeat 10 19-4= 15 stitches, repeat 11 15-4= 11 stitches, repeat 12 11-4= 7 stitches, repeat 13 7-7= 0 stitches, end of the row You'll have a total of 13 pattern repeats as written. I suggest using stitch markers after every couple and occasionally rechecking that each one is a total of 4 stitches. I find that with patterns like this it helps to read the stitches out loud as I work them. This helps me make sure that I'm not missing anything as I work vs finding out at the end of the row.

We’re sorry to hear of your struggles learning lace knitting with the First Timer Knit Lace Scarf. Unfortunately, when learning lace, quite a bit of thinking can be involved. Lace requires a lot of perseverance to learn. However, being a seasoned lace knitter, I do have some tips: 1) Placing stitch markers between each repeat breaks the knitting down into smaller sections, making it easier to identify mistakes sooner. 2) Check your work every row or two, section by section, to look for potential mistakes. 3) Learning to drop down and fix mistakes is an invaluable skill. It is best to learn to do so with the aid of the chart, in my experience. It gives a nice visual as you go. We hope you will try to learn lace knitting again. It’s a great skill to have. In the meantime, taking a break to knit what you already love can be helpful, too. Happy knitting!
