🇫🇷 Mbappe - 9
🇦🇷 Messi - 9
🇪🇸 Villa - 9
🇮🇹 Baggio - 9
From the record of the all time goal scorers in the world cup, kylian Mbappe has the chance to top the record in his life time because he has the opportunity to come for more world cups at least two more, he is still young to play but Messi may not return for it but I'm sure he is satisfied with the records to his name.
Note: I hope you know this is not the complete record for the all time scorers of the world cup. This is the list here

The best scorers of the world football championships can be seen in this list:

So, Klose is currently in first place with 16 goals, but Messi with 13 goals and Mbappe with 12 goals are very close to him.
Messi even scored 4 goals out of 13 from penalties.
I read somewhere that Messi stated that he will play in another world cup, if Argentina becomes the world champion. So, Messi will most likely have a good chance to become the top scorer of the world football championships in 4 years.
However, given that he is still a very young and talented striker, and that he will almost certainly appear in 2-3 more world championships, my prediction is that in 8 years Mbappe will become the best scorer in the world football championships and that record will stand for a very long time.
I think the difference between the link you shared and the one I did was the inclusion of penalty kicks scored but that is not what point I was trying to make. I was trying to talk about goals scored in the time of play and not penalty awarded. Penalty is like a free goal awarded for the player to take the chance of scoring. Freekicks are difficult obviously.
However it will make sense if Messi will come back in Canada, Mexico and USA world cup next tournament. Argentina should be coming as defending champion and that means it is an automatic appearance on the world cup and no competition about that.
He should still be less than 40 years and should be fit for the game, I think the oldest world cup players so far is Essam El-Hadary from Egypt
