Yes because both of them clearly have differences as a specific purpose, online games are just to get pleasure with friends like mobile legend, PUBG etc., while gambling aims to make a profit even though it's not easy but those who are familiar with gambling will always try to get it. Although both of them have in common, the game is online, but both of them have very clear differences we can find in it.
I heard many times that some people said that they play only for fun and not for making money. Now it is better idea for them to play online games instead of gambling for spending time and for fun and entertainment. When there is money involved, you should be very careful about that. Sensible man will never gamble especially with that money which is for his family.
