The writer of Hebrews wrote Heb 2:9
9 But we see Jesus, who was made a little lower than the angels for the suffering of death, crowned with glory and honour; that he by the grace of God should taste death for every man.
Your argument is based upon a translator using every man when in fact the same Greek word πάς is used in John 3:16 which is translated as whoever or whomsoever.
(NKJV) For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life.
(KJV) For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.
The Greek word πᾶς includes the idea of oneness, a totality or the whole. Such as each, every, any, all, the whole, everyone, all things, everything.
Therefore, God so loved the world that He gave His only begotten Son, that whoever-each one/every/any/all/everyone believes in Him should not perish but have everlasting life.
In John 3:16 the Greek word for world κόσμος properly means the inhabitants of the earth, men, the human family.
Heb 2:9 comparison for the Greek word πᾶς
(NKJV) But we see Jesus, who was made a little lower than the angels, for the suffering of death crowned with glory and honor, that He, by the grace of God, might taste death for everyone.
(KJV) But we see Jesus, who was made a little lower than the angels for the suffering of death, crowned with glory and honour; that he by the grace of God should taste death for every man
Both translations work with the definition of the Greek word πᾶς, although 'everyone' is much better in my opinion since it fits 100% contextually to the definition.
In John 3:16, God gave His own Son to the world-the inhabitants of the earth, men, the human family-and everyone who believes will not perish. And in Heb 2:9 that Jesus died for everyone, with God making Him lower than the angels into the form of man.
God gave His own Son for everyone. By doing so, His own Son died on a cross for everyone. Only those who believe God are justified to life, even though God purposed in His Son's death justification to life for everyone. Those who don't receive God's free gift of righteousness are condemned already, for they have not believed in the name of God's Son, the only means for their salvation.
Recap: Only those inhabitants of the earth, men, the human family who receive by faith God's free gift of justification to life in the death of His own Son, who became a Son of Man like them, will not perish. The rest of humanity who disbelieves are condemned, for they have not believed in the only name under Heaven by which a person can be saved.
