Consequences of missing `event` for delegate type?

Question

I'm beginner to C#, I have code where by accident I declared events skipping event keyword. I was sure that this is right code:

using System;

public class Player
{
    ...
    private float money;
    public Action<float> OnMoneyChanged; // missed `event` keyword.

    private void SetMoney(float amount)
    {
        money = amount;
        OnMoneyChanged?.Invoke(amount);
    }
}

public class Level
{
   public Level(Player player)
   {
      player.OnMoneyChanged += UpdateUi;
      ...
   }

   private void UpdateUi(float money)
   {
       ....
   }
}

And that's works perfect, no error, no bugs appear. I knows that formally by skipping event I didn't declare events but normal delegate.

The only drawback I came out is that this mislead other programmer who will read the code, they may conclude that something strange happening here.

The question is: what are the long consequences of missing event for delegate type?
What putting missing event keyword changes?

If you add the event keyword (to Player.OnMoneyChanged), you won't be able to call Player.OnMoneyChanged.Invoke(...) outside of the Player class
