You praying a prayer one time in your life does not mean you are going to heaven unless you act on that prayer thereafter.
Yes, there is the thief on the cross that prayed the prayer and acknowledged to Jesus that he knew who Jesus was and he died that day and went to heaven per Jesus own words.
I am talking here about people that prayed the prayer to receive Jesus into their heart and then ignored Him and went their own way the rest of their life.
This is like the seed that fell on rocky soil.
You must pursue a relationship with Jesus on this earth if you want to be in a relationship with Him for eternity.
If you pursue a relationship with satan on this earth you most certainly will have a relationship with him for eternity in hell where the fire never goes out and the worm never dies.
Choose wisely who you serve and make the wise choice right now, this minute, this second.
