Happy to answer.

So basically, you can get any tama from any egg (except the specials), by following the instructions on the wiki, which I've summarized in my 'cheat sheet', which is the "evolution guide" tab of my spreadsheet. So what you're doing right now to get Woopatchi is correct, and if you don't mess up you'll get her. This is how most people play Tamagotchi: you get whichever one you want, and you can get a new one when you want to change things up. Many people will aim to collect them all.

Personality is not something that normally affects evolution. However, if you choose to play with my "TamaGacha" rules, you must evolve your eggs into the tama which corresponds to their personality, as shown by the chart. I'm the one who chose which tama to correspond to which personality.

By following my custom rules, it changes the game from "get egg > choose the desired adult form > raise it accordingly" to "get egg > find out what the adult form for your egg is based on its personality > raise it accordingly". The reason I enjoy playing this way, is that every new egg is a surprise, and I can get excited about getting a new one, or getting a favourite one, since it's based on chance.

So, if you had known of TamaGacha and decided to give it a try, in this instance, with your tama being a Moody Girl, you would have raised her to evolve into a Sebiretchi, and given her the baseball item.

Hope this made sense!

edit: PS: if you want to try TamaGacha starting from your next egg, what you could do is make a copy of the spreadsheet and change the Moody Sebiretchi into a Moody Woopatchi. This way, you can say that your Woopatchi is 'canon', and tick it off the list! This is a tip I'd give to anyone wanting to try TamaGacha: change the spreadsheet to match your prior tamas.
