In sentences ''they are worth it'' ''I am sorry'' what Tense is being used?

Please first have a look on this thread:

[link]

Check these sentences:

1: They are worth it.

2: We are proud of ourselves.

3: I am sorry.

What tense is being used in above sentences?

In the thread mentioned above gone is being used as an adjective in he is gone. Now I understand that Past Participle can be used as an adjective like gone in he is gone. Therefore, I have no problem with sentence he is gone. But above sentences are again causing problem to me because in those sentences Past Participles are not being used rather simple Present Tense forms are being used. There are a lot of other sentences of this kind and they are always hard for me to understand. If it were up to me then I would like to write above sentences as:

1: They are worthed it.

2: We are prouded of ourselves.

3: I am sorried.

I hope you will understand my problem.

1: They are worth it. I m not sure of this sentence.They worth it seems correct to me.  

2 We are proud of ourselves.Sentences like I am proud of, I am afraid of , I am scared of aren't passive sentences.Here proud, adraid and scared are adjectives.   

3.I am sorry.Here sorry is adjective,too.  I am happy, I am sad , I am clumsy.Happy, sad and clumsy are adjectives.  

You sholdn't change such sentences into passive.In fact they have nothing to do with passive voice.Adjectives like scared, afraid may seem you as the past form of their original one but they aren't.

Is the following sentence correct?

They are worth it.

_Jackson,

_{I think you are trying to learn 2 years worth of English lessons on this forum in a month’s time which is fine if you can digest all the information.  Apparently, you are showing a little indigestion because you are trying to use adjectives as verbs and passive participles.}

_{Let’s see if we can clear up some of the questions you have with an applicable context.}

_{A-    you bought a new sports car and a condo! It must cost you dearly.}

_{B-     I've  worked hard all my life.  I think they are worth it". Or, I think I am worthy of a little rewards. In this context, Both mean “I deserve it”.}

_{This is one of those crazy irregularity of Eng. Worth is a noun. But “worth it” is the correct expression.}

 _{1: They are worthed it. – Don’t be confused with who is "worth it".  I detect a little of that here.}

_{Context: Even though I work  a 12 hour day, when I come to see the smiles on my wife and my kids, I think to myself “they are all worth it”. In this case "they" refer to your wife and kids who are worthy of your hardwork and devotion.}

_{# 2 and # 3 have already been commented so I won't comment anymore.}

This is one of those crazy irregularity of Eng. Worth is a noun. But “worth it” is the correct expression. Question 2: Please explain the above sentence. 1: They are worthed it. – Don’t be confused with who is "worth it".  I detect a little of that here.   Question 3: Please explain the above sentence.
