And not have time for train other girl for fight santa;
Then why are you complaining that you can't beat Santa if you don't train girl that should be fighting? It's not about luck, it's about energy and time management.

I see you have 50 energy slots reserved for skills. Why so much? After a certain time after reset you only need three-four skills that you actually plan to reach this run and which will unlock next girl stages. Skills that require a week or more don't give you anything because you will do a reset before you reach them. You need full skill list only if it is less than 10 hours since your last reset and you didn't get to 28 on most of them yet. Or unless you do a very very long run and even then girls will need 6 out of 10 skills at max. You have 76 total energy, so you must be close to completing Pantless and finished all girls before her, and unlocked next three girls. Pantless requires Acting, Artistry, Body Building. Next 4 girls will also need Tricks, Filming, Humor for first few levels (other skill requirements are 28, so you must have reached those already). You can leave these 6 skills on training and remove the other 4 and you will be able to send 2 more girls to practice (event girl and best girl that you have unlocked). You should always be practicing with your best girl (actually two best girls - one that has higher stats currently and one that has higher potential stats out of those that you unlocked, that will become your next active girl) because if you don't you will just stay behind the crowd and won't be able to reach normal placement. The better your girl the less often you get unwinnable battles in challenge. With 700k/400k/300k Ice I got to tier 18 this run (I usually ended up at tier 12-13 when each battle after win becomes a lose). But even when 50% of battles are losses you still get a lot of cash from them.

each like 10hours the train only get 1770 points in stats
It's 10,302 per 1 day for 10 energy slots on event girl. You need to choose last practice option (4 hour) and use arrows to increase the time amount up to 1 day. I recommend to at least get one or two costumes for your main girls from this event. 75% bonus to all three stats is totally worth the few days of training.

Also you didn't say what rank you are currently in a challenge. Maybe you were lucky and managed to climb high enough already so now most enemies will be hard for you.

I don't know for sure, but this week it actually looks easier to score higher. Even at tier 18 now I still get two 100k-300k girls and one 1M+ out of three tries. Maybe they did tune something or maybe it's just a lucky streak.
