Excuse my English but I will do my best to understand what I want to explain.

I want a farm with more than 100 - 200 accounts but I always have the fear of "ban" .. I have noticed that some people usually buy 1000+ accounts with the tutorial ready,

The "age" of the accounts level 3 has some positive effect with respect to the probability of ban?

The private script has some positive effect with respect to the probability of ban?

it is logical to think that a level 3 account with 10-20 minutes of being created starts to make a money making.

Yes

Yes

Yes

100% YES TO ALL

then I create many "1000+" accounts and wait at least 1 day to use the first 100, and the rest would be more "old" from the time they were created.

It might be time in game and not time since account was made. You may want to try botting lighter / more variety so its less obviously a bot initially. But I mouse record not bot so just my 2 cents.

If you are going to use them for a farm then age wont matter, you will get banned anyway.

Dont bother with the effort of aging an account.

 

Suicide it for 12h+ then scrap it when it gets banned.

I believe ingame time will lower your ban rate, but if you are suiciding them anyway, it's not worth the time to get a little game time on them.
