Home Poker Game Question - Wild card in a 3 Card Guts game

Okay - this is one of the goofy games played on Saturday night.
Our home poker game developed a controversy over a hand dealt in a pot match game. The game is Three Card Guts Poker with low card in the hole wild

Player A was dealt 8-8-A
Player B was dealt 7-7-7
Both players stay in - pot is approx $125
(There is no "House Rule" on natural trips beating a wild card hand)

Player A showed hand and declared 3 Aces - Player B showed hand and declared 3 Aces for a split pot
Player A said Player B did not have a wild card since "there was no low card" and that Player A won and Player B must match the pot ($50 pot match cap)

Do both Players have 3 Aces?
