Can every Pokemon learn at least one Ground type move?

Question

one of my kids in my neighborhood said that every Pokemon can learn at least one ground type move is this true(yes I know about magikarp,ditto, and feebas)

Answer 1

No.

If we follow Fondant's logic on learning Hidden Power allows you to use Hidden Power [Ground], then that just leaves Pokemon that cannot learn by TM, only by level up and Tutor.

Caterpie
Metapod
Weedle
Kakuna
Magikarp
Ditto
Wobbuffet
Wurmple
Silcoon
Cascoon
Wynaut
Beldum
Kricketot
Burmy
Combee
Tynamo

Answer 2

No not true.

Source: I thought about that.(Then realized some Flying types can't learn Ground type attacks)

Can't all flying Pokemon learn sand attack?

No. Case in point, Ducklett/ Swanna.
And technically, all flying Pokemon can learn HP Ground. But that's nit picking. :x
