Only if they say yes do you have the green light to repost it with credit, or share it with your friends. If you're uncertain whether the creator has purposefully turned off downloads, or if it's an issue with the app, simply ask them in the comments of the video-or send a DM-asking for permission to share it. It states that users can't post or send content without the creator's permission. For further information, review TikTok's Intellectual Property Policy. If the creator has explicitly said that they've disabled downloads, you need to respect their privacy by not sharing the video with anyone else.
