First congratulations.

I went from 330 to 200lbs when I was 18.

I have thankfully kept the weight off, been very healthy, and more fit than ever 12 years later... but.... I still have rather loose skin around my tummy. A muffin top of skin is quite easy for me with tighter pants. Thankfully my chest and shoulders are quite wide, but I have a slight “bag” on my nipple tips. This is at 6 foot, 190lbs, and ~14% body fat.

I guess it has tightened some over the years, but nothing near the tightness is see in my thin wife’s or thin friends skin.

I know it’s not great news, but my personal experience.

At end of the day, it could always be worse and you are so much better off even with loose skin for your health and life. Keep an eye on the big picture.
