Politoad's level 70 stat ranges:
So, yeah all of its stats are good. The one you have has a spread that is very possible and it seems legit (I cannot tell exact nature, EVs, or IVs with the given info, just that is has legit stats).
I used Pokemon Showdown!'s teambuilder to find this out
But yeah, unless the OT, ID #, and moveset are shady, it should be fine.
Hope I Helped!
