There is no 50:50 in gambling games because there is house edge, you cant compare it with real coin toss.
he is talking about chance ,you can set your chance to win to 50% and losing to 50% and that would be a fifty fifty bet
difference is that the payout won't be 1:1 so it would be -EV
regarding HE it's of course better to choose low HE games , but at the end what's the point !! you will still lose even if you are playing 0.001% HE game
best thing is to learn poker if you have passion for gambling , and in case you don't have time to learn the game you can always search for good sportsbetting tipsters that were able to profit in the past and just follow what they play
other than that it makes no sense to play unless you are seeking fun
