You want $4 one. Competizione is real high end vidya but it's proper autism: gt3/gt4 only, skill ratings, no mods, they got licenses for entire race classes, you have seasons, blahblah. Original AC is more of a free-form sim, it ranges from competitive racing, through weeb akina runs, to driving free candy van around nurburgring. Anything goes.

For starters, what you want is full assetto bundle (game + all DLC). Game's pretty old and you probably want "Content Manager" to make it playable:

Then it's all good, use it instead of default menus.
