AITAH for telling my friend that she can't be mad about not getting paid for winning a bet?

I'm not fond on gambling, and never have been. This will be important.

Some of my friends are, and its fine because its mostly daft stuff. Stuff like betting a night of babysitting for garden work, or half a muffin for a couple of choccy digestives. One friend (f34) is notorious for trying to get out of paying her due when she loses. She's taken plenty of wins and it has now reached a point where people won't involved her in the games anymore. She was up[set, but didn't care until the world cup came along and money got involved. Not a lot of money, there are rules to make sure no one ends up owing anyone 100s and to keep things friendly.

She promised to behave and she was allowed back in, and did actually pay the first few times she lost, but as the matches progress and she started betting more she suddenly couldn't pay people just yet, or she'd bring it tomorrow and then have a WFH day. The last bet she placed on the england vs France won her a bit of money, but now people are refusing to pay her.

She spent several hours wining at me over messages and here is where I may have been the A***hole. I told her she could be mad about not being paid when she still owed other people their winnings. I she wanted people to hold up their end of the deal, she had to pay her's.

She told me I was just being judgemental because I don't gamble and called me a a***hole.

I don't think I was, but its eating at the back of my mind.
