Yes it is worth putting in the time and effort to create great mobile apps and games. If the people like what you have created and it is properly monetized (Free, free with in app purchases, paid and priced at a point to where you will make a decent profit on sales) then you will be rewarded very nicely for your work. The main issue with many that fail to make sufficient income from their mobile apps is normally down to the experience that is being offered to the user. Your application might be amazing but if it is annoying the end user with ads, buggy, receives slow updates or new features that are implemented are not properly tested then eventually any success a successful application had will die off. Then there are always the short lived applications that are great at first but does not have enough variation of content to keep the user coming back over a long period of time. It has been proven time and time again that anyone that can create a product that people love to use repeatedly over time that adds substantial value to their lives (fun, top quality advice, doesn't bore them, gives them that uncontrollable smile (oh man this is awesome, or mmm just one more level, or let me check appname for that) etc.) has ended up becoming a very nice return on investment for the developer of the application if they own all or most of the IP for the app or have a very good royalty contract setup.
