"I do not like swimming a lot."
Translation:لا أُحِبّ اَلْسِّباحة كَثيراً.
Yes, this sentence is ambiguous in Arabic the same way it is in English. It doesn't specify whether the speaker likes swimming, but doesn't like it much, or whether they like swimming, but not swimming too much.
Hey, thank you O great linguist! I came to the comments wondering precisely that... But I suppose the question was too obvious to even bother asking, so you didn't wait for it and just gave the answer.
