Why do people donate and gift to tiktok battlers?

I've been watching a few live streamers, mostly very chill and small ones (5-20 viewers concurrently). Some of them do battles and it confuses me why anyone gifts. Sometimes it's like a 2 hour stream and 90 minutes of it are "guys tap the screen tap the screen" or "we need one more galaxy guys" or just thanking gifts (in these small streams, usually the same 1-3 people who like to blow money on gifts).

I'm guessing there's zero point in battling, for these small streamers, except to make it like socially acceptable begging? "Gift me so we can win the battle!"

But what I'm not sure about is why people gift or watch streamers where they spend most of the time begging for or thanking gifts. I don't see the entertainment value in that or why anyone would do that. I get it's like paying for attention but it's like a 1 second "thank you for the gift!" And nothing else. Like the streamers I like to watch typically do normal chatting, catching up with regulars, wholesome stuff, nothing weird. Then once they get enough viewers they go into battles and understandably 80% of the people leave.

To me, it's a relationship between an online beggar asking for gifts and a desperate lonely person with disposable money gifting.

Is there something I am not understanding?
