The reason there is confusion about being a righteous or sinful believer, is because that's only a debate among men, but not with God.
With Scripture of God there is only His righteous believers in Jesus Christ, and the unrighteous unbelievers in Jesus Christ.
With the death, burial, and resurrection fo Jesus Christ, God no longer acknowledges transgressors as His people.
In the OT, the natural covenant people of Israel also included both the righteous and the transgressors, seeing that partaking of the covenant was by natural birth and circumcsion.
But in the NT, only with the wholly newbirt of the Spirit, are the holy saints of God amde partakers of His divine nature, and Jesus' holy nation and people.
2Pe 1:3
According as his divine power hath given unto us all things that pertain unto life and godliness, through the knowledge of him that hath called us to glory and virtue. Whereby are given unto us exceeding great and precious promises: that by these ye might be partakers of the divine nature, having escaped the corruption that is in the world through lust.
The OT national Israel had both righteous saints keeping His commandment, and unrighteous transgressors. In the NT nation of Jesus Christ, He only now has His holy believers that keep His commandments,
Rev 14:12
Here is the patience of the saints: here are they that keep the commandments of God, and the faith of Jesus.
2Ti 2:19
Nevertheless the foundation of God standeth sure, having this seal, The Lord knoweth them that are his. And, Let every one that nameth the name of Christ depart from iniquity.
A simple reading of the Old Covenant shows the LORD speaking of His people as sometimes being disobedient and sinners like the unbelieving heathen. But in the New Testament, Scripture never speaks of His justified people being transgressors and sinners like the unbelievers of the world.
1Jo 2:1
My little children, these things write I unto you, that ye sin not. And if any man sin, we have an advocate with the Father, Jesus Christ the righteous:
We righteous believers can sin and transgress by forsaking the faith of Jesus and falling from His grace, but not as a faithful member of His body in the light and holiness of God. If we do transgress, then we are become as the unbelievers of the world, for whom Christ also died and advocates to repent and be forgiven.
Only the sanctified righteous bleievers in Jesus Christ can walk with Him as He walked in righteousness and true holiness. And no man can walk with Jesus by grace, while also sinning and transgressing against Him.
And so, there are only righteous believers in Jesus Christ doing His righteousness, and only sinful believers in Jesus Christ doing unrighteousness against Him.
No believer in Jesus Christ is a sinner and transgressor, and no sinner and transgressor is a believer in Jesus Christ.
Mar 3:33
And he answered them, saying, Who is my mother, or my brethren? And he looked round about on them which sat about him, and said, Behold my mother and my brethren! For whosoever shall be doing the will of God, the same is my brother, and my sister, and mother.
Mat 7:22
Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
