I sometimes have trouble forming sentences and converting my thoughts into words that actually make sense is this an ADHD thing or a Me problem?

Diagnosed recently and I am wondering whether this problem I am having is one of the symptoms of ADHD

sometimes when talking with my friends I would say things that are really not grammatically correct and would say it in the weirdest way but it would still make some sense. some days its worse than others but some days its completely fine and I can speak normally.

"maybe I am just fully a visual learner" - this is an example of something I said to a friend no one says it this way but you can tell what my point is/is trying to be

I also sometimes find trouble understanding people especially if concepts and theories are tough. I really enjoy learning things by myself rather than from a teacher as I can read or listen to it multiple times without people getting annoyed or judging me.

even writing sentences I would have to say the sentence in my head while writing it down and even then I would sometimes miss words so I have to always go back and check if I missed any words while writing.
