You're quoting Strong's out of context.

Used here (all ESV):
Mat 5:22 But I say to you that everyone who is angry with his brother will be liable to judgment; whoever insults his brother will be liable to the council; and whoever says, ‘You fool!’ will be liable to the
hell of fire.
(Notice it is a hell of fire.)
Mat 5:29 If your right eye causes you to sin, tear it out and throw it away. For it is better that you lose one of your members than that your whole body be thrown into
hell.
Mat 5:30 And if your right hand causes you to sin, cut it off and throw it away. For it is better that you lose one of your members than that your whole body go into
hell.
Mat 10:28 And do not fear those who kill the body but cannot kill the soul. Rather fear him who can destroy both soul and body in
hell.
Mat 18:9 And if your eye causes you to sin, tear it out and throw it away. It is better for you to enter life with one eye than with two eyes to be thrown into the
hell of fire.
(Again, it is a hell of fire.)
Mat 23:15 Woe to you, scribes and Pharisees, hypocrites! For you travel across sea and land to make a single proselyte, and when he becomes a proselyte, you make him twice as much a child of
hell as yourselves.
Mat 23:33 You serpents, you brood of vipers, how are you to escape being sentenced to
hell?
Mar 9:43 And if your hand causes you to sin, cut it off. It is better for you to enter life crippled than with two hands to go to
hell, to the unquenchable fire.
Mar 9:45 And if your foot causes you to sin, cut it off. It is better for you to enter life lame than with two feet to be thrown into
hell.
Mar 9:47 And if your eye causes you to sin, tear it out. It is better for you to enter the kingdom of God with one eye than with two eyes to be thrown into
hell,
Mar 9:48 ‘where their worm does not die and the fire is not quenched.’
(Not only is it a hell of fire, but an unquenchable fire.)
Luk 12:5 But I will warn you whom to fear: fear him who, after he has killed, has authority to cast into
hell. Yes, I tell you, fear him!
Jas 3:6 And the tongue is a fire, a world of unrighteousness. The tongue is set among our members, staining the whole body, setting on fire the entire course of life, and set on fire by
hell.
(Another mention of fire in the context of hell.)
So, no, hell and hades are most certainly not the same thing. But the mention of fire in the context of hell sure sounds like it could be a lake of fire, which, hell being the final destination of unbelievers, makes a lot of sense.
