It is normal for PSG to have their Law Odd. Because PSG is a very good team and on the other hand OGC Nice is not a bad team but a much weaker team than PSG. So PSG has more chance to win the match and that's why PSG odds are less. Those who bet on Nice will leave your bet money to their luck due to the high odds, but PSG can be a safe bet even if the odds are low. And that's why most gamblers will bet on PSG. Because no one wants to lose his bet easily no matter how small his profit
Odds for PSG continue to increase before kick off @1.62 for now I have checked the line up and PSG is playing the main squad Mbappe, Rmos and Dembele
Honestly, these are not normal odds for PSG the odds should be lower between 1.2 /1.3 especially PSG playing at home I suspect there is a trap here

I would avoid betting on this match for anyone who bets, don't be too confident there is a possibility that the match will end in a draw.
