This is all 100% normal, with the exception of your minions not loading in when you start which has been a bug in Eternal since around November last year.
The 10 skill points are from your reknown - once unlocked on one character they are automatically unlocked on every new character. The additional potions are also from renown.
If you’ve never (on any character) completed the campaign, I’m not sure how you skipped the campaign during the season - this should have been locked for you until you completed it on one character.
The mount is unlocked because it is a one-time quest on the account now that doesn’t need to be repeated for each character.
The gold will not be from Season 4, it will be from a previous season (if you did those) or previous eternal characters. Season 4 gold gets moved to eternal in a few days.
